Autonomous Driving — In a ‘Flash’

By combining CMOS technology with avalanche photodiodes, researchers at the Fraunhofer Institute for Microelectronic Circuits and Systems IMS (Duisburg, Germany) have developed a potentially cost-effective sensor prototype that aims to support driverless car applications. The “Flash LiDAR” could play a valuable role alongside the cameras, radars, and other components within autonomous vehicles.

ViDAR Optical Radar Provides New Maritime Search Capability

ViDAR, developed by Sentient Vision Systems in Melbourne Australia, provides autonomous, real-time, wide-area search capability, optically, from unmanned aerial vehicles (UAVs) or manned aircraft. ViDAR, which stands for Visual Detection and Ranging, essentially acts as an optical radar, using high-megapixel video or infrared cameras to search the ocean over significantly greater operational coverage areas than can be achieved with current optical sensor approaches.

Machine Vision System Measures ‘Drops’ in Citrus Grove Health

A University of Florida Institute of Food and Agricultural Sciences researcher has developed a machine vision system to measure the quantity of a citrus grove’s dropped and decayed oranges. The fallen fruit provides an indication of a so-far incurable disease that has been spreading through Florida’s trees since its first appearance in the state in 2005.

Customized Drone Maps Glaciers

Using a custom-designed drone, a researcher from The Ohio State University mapped glaciers and wetlands in Peru’s Cordillera Blanca mountain range. Despite a discovered drop in glacier growth, the findings from the unmanned aerial vehicle (UAV) revealed a slightly more optimistic picture of the region’s water supply, which relies in part on the ice formations.

Cambridge Researchers Take Computer Vision for Test Drive

Google's driverless car, like many autonomous vehicles in development, is packed with sensors, radars, lasers, and cameras. To lighten the load of sensing devices in self-driving autos, researchers at Cambridge University have hit the streets with a system that uses only computer vision.

Using Optical Imaging to Combat Counterfeit Components

Counterfeit parts and materials pose a serious threat to the United States defense supply chain. The National Defense Authorization Act (NDAA) of 2012 (Section 818) laid out strict guidelines for DoD prime contractors for detection and avoidance of counterfeit electronic parts1. The Defense Logistics Agency (DLA) identified six federal supply groups in their supply chains that are at high risk for counterfeiting including electrical and electronic components, bearings, hardware and abrasives, pipes and fittings, engine accessories, and vehicle components2. DLA is championing development of anti-counterfeiting technologies that also provide traceability for the parts in its supply chain. A solution called QuanTEK developed by Chromo Logic LLC, involves novel optical imaging methods and has been found to work on a broad class of the DLA identified high-risk federal supply groups.

Manufacturing OLED Lighting

Organic Light Emitting Diode (“OLED”) lighting panels are thin planar area light sources that are naturally diffuse, low glare, high color rendering, cool to the touch, highly energy efficient and highly controllable. Together with LED light sources, they compose the solid state lighting technologies that are replacing over 100 years of bulb and tube lighting technologies, just as solid state electronics have replaced the bulbs and tubes used in electronic devices such as radios, computers and displays.
