Machine Learning Technique Can Rebuild Images That Go Through Multimode Fibers LAUSANNE, Switzerland, Aug. 10, 2018 — Using a deep neural network (DNN) that imitates the way the brain processes images, researchers reconstructed images transmitted over multimode optical fibers at distances of up to 1 km. In the same way the human brain learns to recognize and categorize images and symbols, the DNN was trained to recognize certain images (in this case, handwritten digits) until it was able to recognize other images that were from the same category.
Blue Light Excites Retinal, Intercepts Cellular Signaling in the Eye TOLEDO, Ohio, Aug. 9, 2018 — An optical chemistry research study has shown how blue light from digital devices and the sun can cause the death of retinal molecules, increasing potential for age-related macular degeneration. Photoreceptor chromophore 11-cis retinal (11CR) and...
3D Printing Provides Way to Fabricate Probes Used in Cancer Research ABU DHABI, Aug. 8, 2018 — Researchers at NYU Abu Dhabi have used a 3D printer to create a functional, integrated and inexpensive microfluidic probe (MFP).

‘Time-Folded Optics’ Can Enhance Ultrafast Camera Capabilities CAMBRIDGE, Mass., Aug. 13, 2018 — Researchers have used time as an additional dimension in the design of camera optics, and have demonstrated that by “folding” large spaces in time using time-resolved cavities, new camera capabilities can be added without loss of...
ams VCSEL Used for Android Face Recognition PREMSTAETTEN, Austria, Aug. 11, 2018 — Sensor supplier ams AG announced that its low-power IR vertical-cavity surface-emitting laser (VCSEL) emitter, the PMSIL, is enabling the world’s first implementation of user face recognition in a smartphone based on the Android platform....
Stealth Mark Licenses Oak Ridge Laboratory's Anti-Counterfeiting Technology OAK RIDGE, Tenn. Aug. 10, 2018 — Product authentication technology provider Stealth Mark has exclusively licensed an invisible microtaggant from the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) to fight counterfeiting. The anti-counterfeiting technology features...
Glass Doped with Erbium Could Be Used for Optical Circuits LEEDS, England, Aug. 8, 2018 — A material created by doping glass made from zinc, sodium, and tellurium with the rare-earth element erbium could be used for broadband planar waveguide amplifiers. Scientists have started testing planar waveguides for use in signal transmission in...
Photoacoustic Ultrasound Can Be Used to Measure Periodontal Health LA JOLLA, Calif., Aug. 9, 2018 — Researchers from University of California, San Diego used photoacoustic (optoacoustic) imaging with a contrast agent to measure pocket depths in swine models. The measurements were compared to those taken with a periodontal probe. Results showed...
Low-Level Light Therapy Treats Digital Ulcers MANCHESTER, England, Aug. 9, 2018 — A lamp containing 32 bulbs emitting IR, red, or UV light for use in low-level light therapy (LLLT) was tested on finger ulcers caused by an autoimmune condition. Researcher Michael Hughes, from the University of Manchester, said that the promising...
Silicon-Based Optical Filter Splits Light Across a Range of Wavelengths CAMBRIDGE, Mass., Aug. 7, 2018 — Researchers have designed a new optical filter on a chip that can process optical signals from across a very wide spectrum of light at once. The broadband, low-loss, transmissive dichroic filter can simultaneously achieve single-cutoff operation,...
QCL Frequency Combs May Be the Future of Wi-Fi CAMBRIDGE, Mass., Aug. 13, 2018 — Wi-Fi and cellular data traffic are increasing exponentially, but unless the capacity of wireless links can be increased, all that traffic is bound to lead to bottlenecks. Upcoming 5G networks are a temporary fix. Researchers are focusing on...
