Laser Blasts Viruses In Blood
A new use for lasers has been discovered— zapping viruses out of blood. The technique, which holds promise for disinfecting blood for transfusions, uses a low-power laser beam with a pulse lasting just fractions of a second.

Johns Hopkins University student Shaw-Wei David Tsen says it was during a stroll in the park with his father that the idea was born. Tsen, an immunology researcher in the laboratory of T.C. Wu at Hopkins’ Kimmel Cancer Center, sought a new method to rid isolated blood of dangerous pathogens, including the viruses HIV and hepatitis C. He says current techniques using UV irradiation and radioisotopes can leave a trail of mutated or damaged blood components.
Using ultrasonic vibrations to destroy viruses was one possibility, but his father, Kong-Thon Tsen, a laser expert at Arizona State University, had a better idea: Lasers, unlike ultrasound, can penetrate energy-absorbing water surrounding the viruses and directly vibrate the pathogen itself.
The researchers aimed a low-power laser with a pulse lasting 100 femtoseconds (10-13 second) into glass tubes containing saline-diluted viruses that infect bacteria, also known as bacteriophages. The amount of infectious virus within each cube plummeted 100- to 1000-fold after the laser treatment. “I had to repeat the experiment several times to convince myself that the laser worked this well,” says the younger Tsen.
His laser is different from those emitting a continuous beam of visible light. “Our laser repeatedly sends a rapid pulse of light and then relaxes, allowing the solution surrounding the virus to cool off,” Tsen says. “This significantly reduces heat damage to normal blood components.”
Building on the idea that vibration wrecks a virus’ outer shell, the scientists found that their low-power laser selectively destroys viruses and spares normal human cells around them, while stronger beams kill almost everything.
Father and son speculate that laser vibrations could destroy drug-resistant and -sensitive viruses alike.
Wu says that the technique his student developed “could potentially be used to control communicable diseases by giving infusions of laser-treated blood products.”
The scientists published their results in the July 13 issue of the Journal of Physics: Condensed Matter. They will continue their studies using different viruses.
Says Wu, “We believe this work on bacterial viruses is promising, but the real test will be with more serious pathogens like HIV and hepatitis.”
The National Science Foundation funded the research.

BACKGROUND: Resonant microwave absorption has been proposed in the literature to excite the vibrational states of microorganisms in an attempt to destroy them. But it is extremely difficult to transfer microwave excitation energy to the vibrational energy of microorganisms due to severe absorption of water in this spectral range. We demonstrate for the first time that, by using a visible femtosecond laser, it is effective to inactivate viruses such as bacteriophage M13 through impulsive stimulated Raman scattering. RESULTS AND DISCUSSION: By using a very low power (as low as 0.5 nj/pulse) visible femtosecond laser having a wavelength of 425 nm and a pulse width of 100 fs, we show that M13 phages were inactivated when the laser power density was greater than or equal to 50 MW/cm2. The inactivation of M13 phages was determined by plaque counts and had been found to depend on the pulse width as well as power density of the excitation laser. CONCLUSION: Our experimental findings lay down the foundation for an innovative new strategy of using a very low power visible femtosecond laser to selectively inactivate viruses and other microorganisms while leaving sensitive materials unharmed by manipulating and controlling with the femtosecond laser system.

Researchers in Finland and the US have developed and tested a prototype contact lens that could provide the wearer with a real time hands-free display.
The researchers from the University of Washington and Aalto University, Finland, have constructed a computerised contact lens and demonstrated its safety by testing it on live eyes. At the moment, the contact lens device contains only a single pixel but the researchers see this as a "proof-of-concept" for producing lenses with multiple pixels which, in their hundreds, could be used to display short emails and text messages right into the eye.
The contact lens consists of an antenna to harvest power sent out by an external source, as well as an integrated circuit to store the energy and transfer it to a transparent sapphire chip containing a single blue LED.
The device could overlay computer-generated visual information on to the real world and be of use in gaming devices and navigation systems. It could also be linked to biosensors in the user's body to provide up-to-date information on glucose or lactate levels.
One major problem the researchers had to overcome was the fact that the human eye, with its minimum focal distance of several centimetres, cannot resolve objects on a contact lens. Any information projected on to the lens would probably appear blurry. To combat this, the researchers incorporated a set of Fresnel lenses into the device; these are much thinner and flatter than conventional bulky lenses, and were used here to focus the projected image on to the retina.
After testing the contact lens in free space, it was fitted to the eye of a rabbit, under the strict guidelines for animal use in the laboratory, to evaluate the effect of wearing the contact lens on the cornea and the body in general. In addition to visualising techniques, a fluorescent dye was added to the eye of the rabbit to test for any abrasion or thermal burning.
"We need to improve the antenna design and the associated matching network and optimize the transmission frequency to achieve an overall improvement in the range of wireless power transmission,” said Professor Babak Praviz of the Department of Electrical Engineering, University of Washington in Seattle."Our next goal, however, is to incorporate some predetermined text in the contact lens."

Developed by a team of researchers, energy-momentum spectroscopy allows scientists to better understand how light is emitted from layered nanomaterials and other thin films, possibly leading to better LEDs and solar cells.
A multi-university research team has used a new spectroscopic method to gain a key insight into how light is emitted from layered nanomaterials and other thin films.
The technique, called energy-momentum spectroscopy, enables researchers to look at the light emerging from a thin film and determine whether it is coming from emitters oriented along the plane of the film or from emitters oriented perpendicular to the film. Knowing the orientations of emitters could help engineers make better use of thin-film materials in optical devices like LEDs or solar cells.
The research, published online on March 3 in Nature Nanotechnology, was a collaborative effort of Brown University, Case Western Reserve University, Columbia University, and the University of California–Santa Barbara.
The new technique takes advantage of a fundamental property of thin films: interference. Interference effects can be seen in the rainbow colors visible on the surface of soap bubbles or oil slicks. Scientists can analyze how light constructively and destructively interferes at different angles to draw conclusions about the film itself — how thick it is, for example. This new technique takes that kind of analysis one step further for light-emitting thin films.
“The key difference in our technique is we’re looking at the energy as well as the angle and polarization at which light is emitted,” said Rashid Zia, assistant professor of engineering at Brown University and one of the study’s lead authors. “We can relate these different angles to distinct orientations of emitters in the film. At some angles and polarizations, we see only the light emission from in-plane emitters, while at other angles and polarizations we see only light originating from out-of-plane emitters.”
The researchers demonstrated their technique on two important thin-film materials, molybdenum disulfide (MoS2) and PTCDA. Each represents a class of materials that shows promise for optical applications. MoS2 is a two-dimensional material similar to graphene, and PTCDA is an organic semiconductor. The research showed that light emission from MoS2 occurs only from in-plane emitters. In PTCDA, light comes from two distinct species of emitters, one in-plane and one out-of-plane.
Once the orientation of the emitters is known, Zia says, it may be possible to design structured devices that maximize those directional properties. In most applications, thin-film materials are layered on top of each other. The orientations of emitters in each layer indicate whether electronic excitations are happening within each layer or across layers, and that has implications for how such a device should be configured.
“If you were making an LED using these layered materials and you knew that the electronic excitations were happening across an interface,” Zia said, “then there’s a specific way you want to design the structure to get all of that light out and increase its overall efficiency.”
The same concept could apply to light-absorbing devices like solar cells. By understanding how the electronic excitations happen in the material, it could be possible to structure it in a way that coverts more incoming light to electricity.
“One of the exciting things about this research is how it brought together people with different expertise,” Zia said. “Our group’s expertise at Brown is in developing new forms of spectroscopy and studying the electronic origin of light emission. The Kymissis group at Columbia has a great deal of expertise in organic semiconductors, and the Shan group at Case Western has a great deal of expertise in layered nanomaterials. Jon Schuller, the study’s first author, did a great job in bringing all this expertise together. Jon was a visiting scientist here at Brown, a postdoctoral fellow in the Energy Frontier Research Center at Columbia, and is now a professor at UCSB.”

The main improvement in the new 90°housing version of the pilot is a remarkable reduction in the camera depth. The total depth of the camera body, including the lens mount, is less than 42 millimeters. The pilot 90°has its connectors at the bottom of the camera. Many other small footprint cameras have their connectors at the rear of the camera, which expands their total depth by 20 to 30 millimeters. Taking all of this into account, the pilot fits better in many applications. The cameras with the new housing have the same features as the standard housing pilot cameras. The uncompromisingly high pilot image quality and speed, compared to other small housing cameras in the market, were also transferred to the 90deg models.

Display media technologies have evolved tremendously over the past decades, offering an ever-expanding range of options to enhance visual experiences. From traditional displays like CRT monitors to cutting-edge solutions like holography, each technology offers unique advantages and applications. In this comprehensive guide, we’ll explore the diverse landscape of display media technologies, shedding light on their functionalities, strengths, and limitations.
Cathode Ray Tube (CRT)
Cathode Ray Tube (CRT) monitors were once the standard for display technology, dominating the market for several decades. These monitors work by using electron beams to excite phosphors on a glass screen, creating an image. Though bulky and less energy-efficient than modern displays, CRT monitors are still appreciated for their accurate color reproduction, fast refresh rates, and relatively low input lag.
Liquid Crystal Display (LCD)
LCD displays have largely replaced CRT monitors, thanks to their compact design, energy efficiency, and lower production costs. LCD technology utilizes liquid crystals sandwiched between two layers of glass, with a backlight providing illumination. Images are formed by manipulating the liquid crystals to allow or block light. Although the color accuracy and refresh rates may not be as high as CRT monitors, LCD displays offer high-resolution images with a thinner, lighter form factor.
Organic Light Emitting Diode (OLED)
OLED displays represent a significant step forward in display media technologies, offering improved color accuracy, contrast, and energy efficiency compared to LCDs. Instead of using a backlight, OLED displays rely on organic compounds that emit light when an electric current is applied. This allows for individual pixels to be turned on or off, resulting in deep blacks and a near-infinite contrast ratio. OLED displays are ideal for high-end TVs, smartphones, and other devices where superior image quality is a priority.
Quantum Dot Display
Quantum Dot displays are an emerging technology that utilizes tiny, light-emitting particles called quantum dots. These dots, when excited by a light source, emit specific wavelengths of light, enabling precise color control and high color accuracy. Quantum Dot displays offer improved brightness, color gamut, and energy efficiency compared to traditional LCDs, making them an attractive option for premium TVs and monitors.
MicroLED is a promising display technology that combines some of the best features of OLED and Quantum Dot displays. Like OLED, MicroLED displays consist of self-emissive pixels, eliminating the need for a backlight and providing excellent contrast ratios. However, MicroLEDs use inorganic materials, making them more resistant to burn-in and providing longer lifespans. The technology is still in the early stages of development, but it holds great potential for a variety of applications, including smartphones, TVs, and even large-scale video walls.
Holography is a futuristic display technology that creates three-dimensional images by recording and reconstructing light waves. This technology has the potential to revolutionize various industries, including entertainment, medical imaging, and augmented reality. Though holographic displays are not yet widely available, ongoing research and development hold the promise of a truly immersive visual experience in the future.


Not all “aviators” are the same! Sunglasses – no matter the name – are important for pilots as they protect their most important sensory asset: their sight. According to the Federal Aviation Administration (FAA), “a quality pair of sunglasses is essential in the cockpit environment”. The right pair of sunglasses helps reduce eye fatigue, decreases the effects of harsh sunlight and protects your eyes from solar radiation.
So what makes a quality pair of sunglasses for a pilot? Pilots DO have different needs for their sunglasses. Did you know that exposure to UV radiation increases by about 5% for every 1,000 feet of altitude? Or that polarized lenses (found on many “aviators” today) are not recommended by the FAA because they can reduce or eliminate the visibility of instruments that incorporate anti-glare filters?
We’ve compiled a list of sunglasses we think are best suited for a pilot’s needs:
1. Randolph Aviator Sunglasses. We’re starting this list strong because Randolph Engineering has made a concerted effort to cater specifically to pilots with these sunglasses. Available in several metal frame and lens colors, these sunglasses both retain the classic aviator shape while also providing a glass, non-polarized lens with 98-100% UV protection coating. Many eyewear manufacturers only make one size, but these Randolph Aviator Sunglasses come with a lens width of 52mm, 55mm, or 58mm, so make sure you select the right one for you.


We fabricated a highly water-repellent quartz nanopillar (NP) structure to investigate the effect of varying the contact angle (CA) by using 10-nm-order gaps and 10-nm-diameter NPs. Gaps from 15 to 30 nm led to CAs of more than 100°, showing hydrophobicity, to a maximum of 105°. The mechanism of repelling water on quartz could be explained by the Cassie-Baxter model with a filling factor. A gap of more than 30 nm fills with water due to capillarity, but a gap of less than 30 nm causes water to be repelled by air. We were able to repeatedly fabricate a quartz NP structure with a controllable gap by using a combination of a bio-template and neutral-beam etching and found this structure to be highly water-repellent. The structure has high durability and optical transparency. As a result, we conclude that it can be used in sensors and lenses on various devices such as cameras and radars.

The Swarovski STS 25-50x65 HD Straight Spotting Scope Kits combine their STS 65 spotting scope body with Arca Swiss foot and a wide angle 25-50xWW eyepiece into a convenient bundle.
The Swarovski STS-65 HD Spotting Scope (Arca Swiss Foot) is made with premium fluoride HD lenses that virtually eliminate chromatic aberration. The lenses also feature Swarovski's SWAROTOP ultra anti-reflective coating, resulting in nearly complete light transmission. This scope is also resistant to dust and oil deposits thanks to the SWAROCLEAN coating for reducing surface tension, making the optic much easier to clean; less cleaning means a longer lasting scope! Aside from the lens coatings, all glass surfaces of the prisms and lenses are treated with the SWARODUR coating that reduces reflection to a minuscule 0.2% for the highest contrast throughout the visible light spectrum. This model is compatible with any tripod head containing an Arca Swiss mount socket, eliminating the need for a plate. The helical focusing knob is more ergonomic than traditional, smaller focus wheels. The sleek green armor covering the glass eliminates the need for a case.
The Swarovski 25-50xW Eyepiece displays a much wider angle at 25x than the 20-60xS eyepiece does at 20x, giving a field of view ranging from 126 feet (25x) to 81 feet (50x) at 1000 yards. It also has a larger image circle. All of this means that it will reduce the likelihood of vignetting while digiscoping. Eye relief is a generous 17mm.

RunCam recently released an improved version of the most popular FPV camera (Sony 600TVL PZ0420 Camera), the Runcam PZ0420M.
Get your Runcam PZ0420M camera from Runcam.com!
To summarize, this camera has been optimized in:
- Wider voltage input (supports 2S to 4S Lipo battery)
- No more fragile resonator hanging around (used to cause lots of problems, easy to snap in crashes)
- Smaller form factor, size reduced down to 28mm x 28mm (in fact I don’t know if this is a good thing, lots of frames are designed for the original dimension: 38mm x 38mm and breakable to 32mm x 32mm)
- 3 grams lighter, weights at 11.8g.
I got to say, this camera is Superb, probably one of the best FPV camera I have used to date! Image quality is just great for FPV. I flew directly into the sun, and everything else is still visible. Flew into the forrest, and wide range dynamics works well, and lighting adjustment kicked in very quickly. Here is some footage of this camera.
With some little changes in setting below, it performs even better for me:
- Factory Reset
- DWDR on, level to 63.
- Select LCD display
- Gamma 0.55
- Added brightness +5
- Sharpness maximum
With the smaller size, I think it could make a good camera for 180 mini quad. I used this camera on my Demon Ghost 220 mini quad, the camera mount was designed for ordinary size board camera (34mm), but i still managed to mount it on with cable ties (not easy though :) )
Also note that the camera lens is about 2-3mm longer than the older version, despite the smaller size, so mind the lens sticking out of the frame when you are mounting it. Here is the manual that comes with the camera.

An optically pumped vertical-cavity surface-emitting laser (VCSEL) that emits in the mid-IR at above room temperature in pulsed mode could have far-reaching implications for chemical analysis and atmospheric pollution monitoring.Nearly all gas molecules, including a number of important pollutants, have their strongest absorption in the mid-infrared portion of the spectrum. Therefore, the sensitivity of gas detection using mid-IR radiation is several magnitudes higher than it is using near-IR. No semiconductor laser emitting in the mid-IR, however, comes close to the performance or the stability of its near-IR counterparts.Researchers have demonstrated an optically pumped vertical-cavity surface-emitting laser that operates in the mid-IR at room temperature. The laser source may find application in the sensing of atmospheric pollutants. Courtesy of Frank Zhao, University of Oklahoma.Now a team at the University of Oklahoma in Norman is bridging the gap. Zhisheng Shi and his colleagues have demonstrated an optically pumped multiple-quantum-well VCSEL emitting at 4.12 µm with a room-temperature gain peak. By applying the vertical-cavity structure to lead-salt materials, they reduced the laser threshold, improved the heat dissipation and overcame problems such as mode-hopping and multimode operation. And, compared with previous efforts, the gain peak and the cavity mode of the VCSEL are closely matched at 300 K.This is important because the thickness of the active semiconductor materials determines the possible wavelengths of the laser emission. When the thickness is right, Shi explained, only one cavity mode is allowed, resulting in the emission of a single wavelength. At the same time, a semiconductor material that favors emission at a specific wavelength is said to have a "gain peak" at a specific temperature.The researchers carefully controlled the thickness of the active semiconductor material in the stack, which they grew by molecular beam epitaxy, so that the VCSEL operated at peak power at room temperature. To enable the pump radiation to reach the active region between the two mirrors, they engineered the lead-salt materials to be transparent to 1-µm radiation from the pump source. In the experiments, an Nd:YAG pumped the VCSEL, but because high-power semiconductor lasers emitting at that wavelength are commercially available, the work promises a compact diode-pumped mid-IR laser system in the not-too-distant future.Such a system still is most likely two to three years away, but Shi said that the work could usher in a number of improvements for mid-IR lasers, such as continuous-wave operation, spectral purity and superior beam quality. In the meantime, the team will refine the VCSEL structure to reduce threshold and to eliminate transverse modes.

Professor Hiroshi Amano was the third keynote speaker at DisplayWeek and he discussed Nanorod LEDs in the display field. However, he started by pointing out the contribution of LEDs in reducing power use in applications such as lighting. Low power lighting can make a dramatic impact on development in many areas of the world where mains power is not available. There are many applications for LED and he showed a roadmap for the development of devices and applications.
Amano is working in a development lab in Japan that has many facilities ‘under one roof’ for the development of LEDs. The group has collaboration with researchers in Korea as well.
There is a problem with LEDs when they get below 10µm per side as then the external quantum efficiency drops because of surface recombination at the side wall. That means that a new approach is needed and he favours Gallium Nitride (GaN) nanorods. Higher efficiency is needed for 8K displays because of the low efficiency of current LCDs.
He believes that this technology is likely to become an option for display use in the future. This is especially when the display resolution of future consumer electronics products is required to increase to 8K. The chip dimension of MicroLEDs should be smaller than 1?m so as to match with the display of a cellphone with extremely high resolution. Whether quantum dots or phosphor is used to convert from blue LED light, either will face a big technical obstacle to achieving a coating that will achieve color conversion on such a tiny chip. (We have already reported that particles of traditional phosphor are already too big for really small microLEDs)
Certainly, such technology will not be appropriate for the existing LED production process, so the equipment that grows the epitaxial wafer is required to be modified. However, as for the mode of growing an appropriate epi wafer structure, a structure with dissimilar materials should be slowly grown through what he called “the interlace mode between injection and interruption”. The intention of the process is to achieve RGB full-color light from one wafer. Then, when can the production of this highly advanced technology come true? Let’s hope to see it during our lifetime, Amano said.
To make something like the Cledis concept for wearable display applications, the LED should be less than 1 micron on each side. Sony’s Cledis is great, Amano said, but it’s just too big for many applications. The power efficiency, considering the high quality is good, however.
Nanorod LEDs can be made much smaller than traditional LEDs and can be made using MOVPE, although carbon can get in which causes a problem. Because of this, it’s best to use a pulse mode, Amano said. He then went through some of the manufacturing processes.
Phosphor particles are bigger than the rods – but with QD phosphor it will be very hard to get a good black, Amano said (presumably because of the problem of photon-driven emission).
You can control the wavelength of the light from quantum rods with the height of the rod and with indium incorporation. So you can make RGB using the same substrate and process. The shape of the rod can be controlled to allow the emission of four different wavelengths of light. The balance between the colours is controlled by the current applied.
At the moment, the green being produced is a blueish colour and the red is really orange, so more development is needed.
The key point is that you may be able to make all colours with a single architecture, he concluded.

Diode Laser-Based Detection of Combustor Instabilities with Application to a Scramjet Engine
Journal article (postprint)
AIR FORCE RESEARCH LAB WRIGHT-PATTERSON AFB OH PROPULSION DIRECTORATE
Pagination or Media Count:
Fluctuations in temperature non-uniformity along the line-of-sight of a diode laser absorption sensor in a model scramjet are found to precede backpressure-induced unstart expulsion of the isolator shock train. A novel detection strategy combining Fourier analysis of temperature time series to determine low-frequency heat release fluctuations with simultaneous measurements of multiple absorption features of H2O to identify temperature non-uniformities was applied to the scramjet combustor. Time-resolved absorption is measured using wavelength modulation spectroscopy for three transitions chosen with different temperature-dependent absorption characteristics. The line-of-sight LOS-averaged temperature inferred from the ratio of absorption from one pair of transitions is highly sensitive to low-temperature nonuniformities along the absorption path while the other ratio is less sensitive. The fraction of fluctuations in the range 1 f 50 Hz is determined from short-time Fourier transforms STFTs of the measured temperatures from both transition pairs.

This paper describes work supporting the development of a high intensity laser power beaming (HILPB) system for the purpose of wireless power transmission. The main contribution of this research is utilizing high intensity lasers to illuminate vertical multi-junction (VMJ) solar cells developed by NASA-GRC. Several HILPB receivers are designed, constructed and evaluated with various lasers to assess the performance of the VMJ cells and the receiver under a variety of conditions. Several matters such as parallel cell back-feeding, optimal receiver geometry, laser wavelength, non-uniform illumination and thermal effects at high intensities are investigated. Substantial power densities are achieved, and suggestions are made to improve the performance of the system in future iterations. Thus far, the highest amount of energy obtained from a receiver during these tests was 23.7778 watts. In addition, one VMJ cell was able to achieve a power density of 13.6 watts per cm2, at a conversion efficiency of 24 . These experiments confirm that the VMJ technology can withstand and utilize the high intensity laser energy without damage and/or significant reduction in the conversion efficiency

History of optical fiber
Point to point fiber optic transmission system is connected via fiber optic cable. May include a fiber optic cable (sometimes called single fiber) or 2 fiber (sometimes called dual-fiber), or even more (48-fiber, fiber 1000)Humanity has never given up on finding the ideal optical transmission medium, and make unremitting efforts, it was discovered that a highly transparent quartz glass can pass light. This is called the optical glass fiber, referred to as "fiber." People use it to create a medical on the use of the endoscope, for example made of endoscopy, can be observed in about one meter away from the situation in vivo, but it's a great loss attenuation, can only send a short distance is the degree of light loss per kilometer of measured in decibels, until the 1960s, the best glass fiber attenuation loss per kilometer 1000 db is still more than 1000 db of loss per kilometer What does the concept of loss of 10 db per kilometer is the input signal transmission 1 km after only one-tenth, 20 db, says only one per cent, 30 db is the only one-thousandth of ... ... 1000 dB, meaning that only one per cent billion, is whether how communication can not be used, so there were many scientists and inventors that little hope of glass fiber communication, loss of confidence, to give up the study of optical fiber communications.The invention of lasers and fiber, so that people see the dawn of optical communications. In order to achieve optical fiber communication, but also the performance in laser and optical fiber on a major breakthrough, but a breakthrough in these areas encountered many difficulties, especially in fiber-optic loss of communication can be used to achieve the requirements of loss per kilometer from 1000 db to 20 db reduction seems unlikely that many scientists have lost the realization of optical fiber communication confidence in this case, was born in Shanghai by the British Chinese Kao (KCKao), Ph.D., through the British Standard Telecommunications Laboratories in numerous studies made on the basis of Lightwave made a bold idea, he believes that since the power can be transmitted along a metal wire, the light should be able to along the optical glass fiber transmission .1966 July, Kao's outlook on the optical transmission of great historical significance of the papers, the paper analyzes the main reason for the glass fiber loss of large, boldly predicted that, as long as to lower the glass fiber impurities, it is possible to make fiber loss per kilometer from 1000 db to reduce to 20 dB / km, making it possible for communication. this paper, scientists in many countries are encouraged to strengthen the efforts to achieve low-loss optical fiber of confidence.The world's first a low-loss silica fiber - 1970, Corning Glass Company's three U.S. researchers Marui Er, Caplong, Keck successfully made the transmission loss is only 20 dB per kilometer fiber. What is the concept of it and use it to compare the degree of transparency of glass, optical power loss through the glass half (equivalent to 3 dB) in length are: ordinary glass of a few centimeters, the most advanced optical glass, only a few meters per thousand through m loss of 20 dB up to 150 m length of fiber, which means that the degree of transparency is already higher than fiber glass than a few hundred times! at the time, made such a low loss optical fiber can be said to amazing move, which marks the optical fiber for communications with the realistic possibility.

Analytical modeling of micromachined mechanical resonator sensor selfexcited by cw laser irradiation is presented. The optical feedback through the photothermal effect in the interference fringe generates the selfexcited vibration of the micromachined beams. The optical interference, thermal diffusion in the resonator and mechanical dynamics of the resonator are combined to maintain the oscillation. From the analysis, the following phenomena of the selfexcited vibration have been explained: (1) Threshold in light intensity to generate the vibration, (2) Saturation of the vibration amplitude, (3) Periodicity of the vibration excitation as a function of the displacement of the feedback mirror, (4) Bistability of the vibration center, (5) Frequency shift of the vibration.

Nowadays ultrafast fiber laser systems have reached a new level in modern technologies. And recently a German company announced that they have developed a new fiber laser that had a perfect laser beam quality, high process technology and could be bought with average powers of more than 100 W from stock.
At the end of the 2018th, a team of researchers has demonstrated their latest record that was a fiber laser system with 3.5 kW average power and a pulse duration of 430 fs after amplification. Moreover, the laser system has an automated spatial and temporal alignment of the interferometric amplification channels.
It should be noted that the novel fiber laser technology is based on an all-fiber amplifier that employs a coherent combination of four separately amplified laser beams. Herewith, this fiber laser creates pulses of 1047 nm wavelengths and a repetition rate of 80 MHz. Then these pulses are divided into 4 separate laser beams and go into the amplifier.
The point lies in the process of amplification after which the fiber laser beam looks really nice. Nevertheless, the researchers are planning to increase the system up to 10 kW later this year. At the same time, the laser systems have numerous advantages such as:
- Efficient heat dissipation;
- Excellent output laser beam quality;
- Compactness and ruggedness;
- Reduced mode distortion;
- Reliable and low-cost technology;
- Fiber lasers ensure accurate cutting and a quite high edge quality;

单目标跟踪是计算机视觉领域中的研究热点. 传统算法如相关滤波的跟踪速度较快, 但由于提取到的颜色、灰度等手工特征较为粗糙, 跟踪精度往往不高. 近年来随着深度学习理论的发展, 使用深度特征的跟踪方法能够在跟踪的精度和速度方面达到很好的平衡. 本文首先介绍单目标跟踪的相关背景, 接着从相关滤波单目标跟踪、深度学习单目标跟踪两个阶段对单目标跟踪领域发展过程中涌现出的多个算法进行梳理, 并详细介绍目前主流的孪生网络算法. 最后通过大型数据集对近年来优秀算法进行对比分析, 针对其缺点与不足, 对该领域未来的发展前景做出展望.
Single object tracking is a research focus in the field of computer vision. Traditional algorithms including correlation filtering have fast tracking speed but generally low tracking accuracy due to the roughness of extracted manual features such as color and gray levels. With the development of deep learning theory in recent years, tracking methods using deep features can achieve a good balance between tracking accuracy and speed. This study first introduces the relevant background of single object tracking and then sorts out multiple algorithms that have emerged in the development of single object tracking from the two stages of single object tracking based on correlation filters and deep learning. The current mainstream Siamese network algorithms are also introduced in detail. Finally, a large data set is used to compare and analyze the excellent algorithms that have emerged in recent years. In view of the shortcomings and deficiencies of these algorithms, the development prospects of this field are provided in this study.


Lithium Niobate Q-SwitchesThe G&H electro-optic Q-switch employs the highest optical quality lithium niobate available. The electro-optic effect of lithium niobate makes it extremely useful for Pockels cell Q-switching of several laser types including Nd:YAG, Nd:YALO, Nd:YLF and Er:YLF. Lithium niobate Q-switches are used in both military and commercial applications, including target designating, range finding, and ophthalmic surgery. Our crystals offer low loss, high contrast ratio, and low wavefront distortion, and are qualified for use at 300 MW/cm2. The temperature-stable (TS and XTS) versions of our electro-optic LN Q-switches allow operation over a wide range of temperatures while maintaining excellent contrast ratio.
An electro-optic Q-switch can be used to modulate the loss in a laser cavity to generate high intensity, pulsed laser light. When an electromagnetic field is applied to an electro-optically active crystal such as lithium niobate (LN), a change in refractive index proportional to the electric field known as the Pockels effect is induced. Light passing through the active crystal experiences a phase change proportional to the interaction length, altering its polarization. By placing the crystal between a pair of cross-polarizers, light can be passed or blocked at very fast switching speeds. This allows a G&H lithium niobate crystal to be used to create a Pockels cell for modulating light intensity within a laser cavity, to achieve Q-switching and generate very short, intense laser pulses. A high quality EO Q-switch has several important characteristics:
- Very low loss in the “off” state to maximize output intensity
- High contrast ratio between “on” and “off” states
- Ability to withstand very high peak laser power
Ensuring Temperature stabilityTemperature stability is of primary importance in selecting an EO Q-switch, leading to the introduction of our TS and XTS temperature stable product series. A typical lithium niobate Q-switch suffers from pyro-electric charge buildup when operated in the cool environments often seen in aerospace, leading to premature lasing. While radioactive americium can be used to ionize the air around the crystal and bleed off the charge, handling and disposal of these materials are problematic. We use a proprietary thermo-chemical reduction technique to increase conductivity of our LN crystal faces, thus dissipating charge and eliminating the premature lasing effect. While this process increases insertion loss slightly, it allows our temperature-stable TS and XTS Q-switches to be used as they are over a wide range of operating temperatures while maintaining excellent contrast ratio.
EO vs AO Q-switchingQ-switching can also be achieved via the acousto-optic effect. An AO Q-switch operates at MHz switching speeds, while an EO Q-switch allows GHz switching. Depending on the size of the crystal face and interaction length, an EO Q-switch may require higher power than an AO Q-switch. A larger beam size requires that higher power be applied to the EO crystal, but this can be mitigated by using a longer interaction length. Support from G&H engineers ensures each customer receives the best fit to the application, from rugged range-finders to sophisticated ophthalmic surgery systems.
Applications of Lithium Niobate Q-SwitchesRange-finders, target designators.

StellarNet’s line of research grade fluorescence systems are designed for a wide range of applications requiring eXtreme sensitivity. Choose from our research grade BLACK-Comet with concave grating optics or our high performance SILVER-Nova with Thermo Electric Cooling (TEC). Sample types include powders, liquids, films and surfaces and there are options for cuvette, probe, and/or flow cell accessories. As always, StellarNet instrumentation is built modularized, compact, and rugged for field, process, or lab environments.
The compact spectrometer is the main component of the system and is preconfigured with high throughput optics and a larger entrance slit, low noise circuit design, and an ultra-sensitive detector array for extreme low-light level detection from 200-1100nm.
BLACK-Comet concave grating spectrometers have ultra low stray light and enhanced sensitivity due to their superior grating technology. As opposed to the industry standard Czerny Turner optical design used in most miniature spectrometers, which employ mirrors and a plane grating, the BLACK-Comet’s concave grating is the sole element in the optical grating design, thus reducing the amount of surfaces in the light path. Scattered light is thus drastically reduced to 0.02% at 435 nm and 0.2% at 200 nm. The BLACK-Comet grating has an f-number of f/2 which provides nearly 4-5 times the system light collecting ability compared to competing models with f-numbers of f/4 and f/5. Additionally, the aberration corrected grating provides broadband uniform resolution and excellent spectral shapes. BLACK-Comet TEC models with advanced cooling options will be available in 2016!
StellarNet’s SILVER-Nova wide range spectrometer includes an integrated thermo electric cooler (TEC) added to the detector array to maintain -15 °C from ambient and achieve a +/-0.1 °C temperature stabilization increasing the S/N ratio by 60% at long exposure times, thus dramatically enhancing the instruments dynamic range. Also, the SILVER-Nova contains a large detector lens assembly increasing photon collection ability by 3-4x with 600 and 1000 micron diameter input fibers. These design optimizations make the SILVER-Nova TEC spectrometer one of the premier miniature spectrometers for low light detection.
StellarNet fluorescence systems are rugged and shock-proof with no moving parts and are suitable for field applications, factory and industrial conditions; even perfect for a standard laboratory benchtop!

Glass waveguides are fabricated using laser processing techniques that have low optical loss with >90% optical throughput. Advanced light pipes are demonstrated, including angled facets for turning mirrors used for lens-to-light pipe coupling, tapers that increase the concentration, and couplers for combining the outputs from multiple lens array elements. Because they are fabricated from glass, these light pipes can support large optical concentrations and propagate broadband solar over long distances with minimal loss and degradation compared to polymer waveguides. Applications include waveguiding solar concentrators using multi-junction PV cells, solar thermal applications and remoting solar energy, such as for daylighting. Ray trace simulations are used to estimate the surface smoothness required to achieve low loss. Optical measurements for fabricated light pipes are reported for use in waveguiding solar concentrator architectures.
New applications for light pipes include waveguiding solar concentrators. For practical applications, achieving high optical transmission is critical so low-absorption glass is preferred over other materials, and the fabrication approach must show promise for scalability and low manufacturing costs. We present results for fabricated fused silica light pipes using femtosecond laser irradiation followed by chemical etching. After compensating for Fresnel losses and averaging over incident angles (in air) from 0° to 25°, transmission efficiencies of 96% and higher were measured for light pipes up to 20mm in length and 1mm2 cross-sectional area. The feasibility of creating glass light pipes with advanced geometries such as angled facets, tapering of the cross-section along the length, and combiners with micron-scale precision is also demonstrated. Tapered light pipes with concentrating factors up to 7x were fabricated, as well as cascaded structures with 45°-angled facets to couple light from multiple lens array elements into a common light pipe.

Calibrated and affordable colorimeter performs better than a spectroradiometer for gamma correction. Computer-controlled, bus powered USB colorimeter with an easy to use cross-platform software interface, designed for characterising and calibrating your CRT or LCD monitor.
Display linearization can be a time consuming, manual procedure, but ColorCAL helps to make it automated and fast. This compact USB colorimeter measures CIE chromaticity coordinates and photopic luminance. The data is returned via a virtual serial port interface which is straightforward to control and incorporate with a wide variety of software. Each unit is carefully calibrated using a spectroradiometric device and appropriate light sources; the units contain multiple calibration matrices for use with CRT and LCD monitors. This approach provides the best possible accuracy at a very affordable price. A TTL compatible, photodiode style output provides an elegant way to generate screen based triggers. This feature can aid in characterising signal processing delays (input lag) in LCD monitors, projectors and other digital display technologies, which if undetected might introduce a confound in experimental results.
