Choosing a Light and Color Measurement System for LEDs

LED-based lighting and display systems are becoming increasingly popular due to their low cost, flexibility, and efficiency. Measuring the light and color output of LEDs is, therefore, becoming more important as their performance is compared to and evaluated against traditional technologies. In addition, inherent performance variations from device to device must be understood and controlled.

Miniature Camera Mimics Eagle's Eye

A tiny, 3D-printed “eagle-eye” camera developed at the University of Stuttgart in Germany mimics the vision of some of nature's sharpest predators. The “foveated” imaging system, named after the fovea part of the eye, provides a high central acuity that could support new applications in optical sensors, endoscopy, and surveillance drones.

Custom Brakes Meet the Challenges of Gearless Motor Elevators

Standard braking systems could not meet the difficult speed, energy, and dynamic torque constraints.

A manufacturer of low and high-rise elevators faced a challenge when customers began calling for a flexible elevator to meet the needs of the growing mid-rise, mixed-use building market. The global construction boom of mid-rise buildings can be attributed to several factors. Developers are more apt to build “short” because it requires less capital and the time to get permits approved is reduced considerably, especially in developing countries.

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.

NASA Navigation Sensor May Land in Applications Beyond Mars

Although a NASA-built sensor being tested in the Mojave Desert this summer will be used to support the safe landing of rovers on Mars, one of the technology's lead researchers sees other commercial possibilities. Principal Investigator Farzin Amzajerdian and his team at NASA's Langley Research Center developed the Navigation Doppler Lidar, a bread-box-sized sensor system that could someday play a role in aircraft navigation and even driverless car applications.
