Corrective 'Eyeglasses' Created For X-Ray Research Facilities

Even when an X-ray beam is steered and focused with advanced mirrors and other optics, abnormalities can creep in. These problems have names familiar to those with imperfect vision, such as “astigmatism” or “coma” and “spherical” errors. And just like our eyes, an X-ray beam can lose power and focus when its alignment isn’t perfect. To address this challenge with X-rays, researchers designed and built special spectacles, or corrective phase plates, for use at light sources that use high-intensity X-rays to probe matter in fine detail.

Advanced Sensor Enables Ultrafast Camera for Self-Driving Vehicles and Drones

Scientists from Nanyang Technological University in Singapore developed an ultrafast high-contrast camera that could help self-driving cars and drones see better in extreme road conditions and in bad weather. Unlike typical optical cameras, which can be blinded by bright light and unable to make out details in the dark, NTU’s new smart camera can record the slightest movements and objects in real time.

High-Power Fiber Lasers

New Applications Are Being Enabled by Dramatic Advances in Design and PerformanceHigh-power (multi-kW) fiber lasers are revolutionizing industrial materials processing markets by offering an unmatched combination of performance, reliability, and cost advantages. For example, in sheet metal cutting (the largest application, with more than $1B/year of laser sales), fiber lasers provide the highest cutting speed (especially for thin sheets, the dominant application), scalability to thick sheets (>1”), and the ability to process a wide range of metals with a single tool. Along with low power consumption and high reliability, these capabilities result in the lowest cost per part. Fiber lasers have thus been the fastest-growing segment of the laser market for the past decade.

Finding the Right Chip-on-Tip Camera Technology

You have a great idea that could potentially revolutionize your industry: a new surgical technique, diagnostic solution, or inspection system. You already know getting there will require the latest video imaging technology from an incredibly small, sub-millimeter, package; in other words, a distal chip-on-tip (COT) video camera. The COT needs to integrate into an elegantly designed, flexible device and allow video imaging into anatomy that was previously inaccessible, or image into the tiny dark crevices of our mechanized world. The technology has to be inexpensive, yet video performance needs to be competitive with larger sensor video products with which the market is already familiar. (Figure 1). So, where do you start to identify appropriate video technologies and vendors?

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.
