A New Laser Beam Steering Device for Autonomous Cars - Novus Light Technologies Today

A University of Texas astatine Arlington electrical engineering prof is starring a task that volition research an optical laser beam steering instrumentality for 3D sensing successful autonomous driving cars.

To marque the device, Weidong Zhou, UTA prof successful the Department of Electrical Engineering, volition usage a four-year, $400,000 National Science Foundation assistance titled “Fast 2D Beam Steering Device Integrated Directly connected High Power VCSEL Arrays.”

“We’re investigating an optical beam steering instrumentality based connected the electrical tuning of photonic crystal cavities, a benignant of nanophotonic structure, that tin beryllium designed to manipulate airy beams,” Zhou said. “Right present astir existing methods usage mechanical movements to steer the airy beam direction. That’s dilatory and bulky. What we’re doing is overmuch faster, precise compact and much reliable.”

High-speed beam steering is important successful galore emerging applications, including autonomous driving, augmented reality, escaped abstraction communications, 3D sensing and imaging systems. Zhou said the vertical-cavity, surface-emitting laser (VCSEL) utilized successful the task is besides recovered successful machine mice, fibre optic communications, look identification, astute phones, laser printers and astute glasses.

“VCSEL arrays tin supply a disruptive exertion for high-performance laser detection and ranging systems,” helium said. “In addition, the task offers a level for pupil acquisition and grooming and helps workforce mentation successful photonics and optics, semiconductors, sensing and imaging, nanotechnology and manufacturing.”

Diana Huffaker, seat of the Department of Electrical Engineering, said the exertion for Zhou’s task could scope the full semiconductor sector.

“A new-age optical beam steering instrumentality would velocity up truthful galore aspects of the semiconductor world,” Huffaker said. “It could revolutionize that satellite successful making existent operations truthful contiguous and truthful effortless.”
