Glass creates resilient and high-performing graphene
Three teams of scientists are using glass in research projects that could bring graphene into the mainstream, allow windows to function as screens and produce ultra-slimline smartphone cameras. Scientists at the US Department of Energy's Brookhaven National Laboratory have developed a simple and powerful method for creating resilient, customised and high-performing graphene by layering it on top of common glass.
Satellite alerts can track small-scale deforestation
With data from satellites, there is generally a trade-off between resolution and the frequency of updates. This is the reason why most of the alerts already on Global Forest Watch, an interactive online forest monitoring and alert system designed to empower people everywhere with the information they need to better manage and conserve forest landscapes, are 500 or 250m resolution.
NASA to build first integrated-photonics modem
A NASA team has been tapped to build a new type of communications modem that will employ an emerging, and potentially revolutionary, technology that could transform everything from telecomms, medical imaging and advanced manufacturing to national defence. The space agency’s first-ever integrated-photonics modem will be tested aboard the ISS from 2020 as part of NASA’s multi-year Laser Communications Relay Demonstration (LCRD).
Optical lens promises to revolutionise technology
A flat optical lens just a billionth of a metre thick will let us see living creatures as small as a single bacterium better than ever before. The new lens, developed by researchers at Swinburne University of Technology, promises to revolutionise much of the technology around us.
Enhancement of location accuracy down to centimeters
Researchers at the University of California, Riverside have developed a new, more computationally efficient way to process data from the GPS, to enhance location accuracy from the meter-level down to a few centimeters. The optimisation will be used in the development of autonomous vehicles, improved aviation and naval navigation systems, and precision technologies.
Imec introduces broad spectrum hyperspectral imaging solutions
At SPIE Photonics West, imec will present a new set of hyperspectral sensor and camera solutions with extended spectral range, going from the visible light (VIS) up to near infrared (NIR). The new line-scan VNIR (visible to near-infrared) sensor and snapshot mosaic VNIR camera outperform current solutions in spectral range and compactness.
New competition identifies innovation in aerospace
Commercial low-Earth-orbit (LEO) satellites are about to witness tremendous economic growth. Last year, hardly a month passed without the announcement of another satellite constellation designed to support Earth observation or broadband communication. Compared to those in more distant orbits, LEO satellites offer shorter orbiting periods and multiple daily flyovers thanks to their close proximity to Earth. This opens the door to an intriguing mar...
'Worlds first' high speed laser communication satellite
Via EDRS-A and EDRS-C communication relay satellites, the SpaceDataHighway will be able to transfer information (images, video, data collected by sensors) from Earth observation satellites, UAVs and surveillance aircraft, or even from a space station such as the ISS.
Satellite navigation system antenna provides wireless signal reception
Pulse Electronics Corporation's Monarch series multi-mode global navigation satellite system ceramic antennas provide wireless signal reception for the four major global and regional satellite systems: GPS, GLONASS, Beidou (Compass) and Galileo. The Monarch series W3010 is a compact, low profile antenna that delivers high efficiency (75% typical) over a wide bandwidth for enhanced navigation and device tracking.
Strong turnout of next-gen products at Photonics West 2016
