JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]SOUTHAMPTON, England, Feb. 12, 2021 — Researchers from the University of Southampton, in collaboration with a team from San Francisco-based nanotechnology company PointCloud Inc., developed a scalable 3D lidar imaging system that the collaborators said matches and exceeds the performance and accuracy of most mechanical systems currently in use. The cost-effective device may provide a path to large-volume production of compact, inexpensive, and high-performance 3D imaging cameras for use in robotics, autonomous navigation systems, mapping of building sites to increase safety, and health care. The integrated system, developed...Read full articleRelated content from Photonics MediaArticlesVisitech Acquires Keynote Photonics: Week in Brief: 07/15/22Northrop Grumman Corp. completed the preliminary design review for a high-energy laser prototype that will feature an architecture scalable to more than a megawatt for the U.S. Department of Defense....Photonics.com 7/15/2022Swave Photonics Takes Top Prize at 2023 SPIE Startup ChallengeSwave Photonics, a Silicon Valley-based developer of holographic extended reality (HXR) technology, earned the $10,000 top prize in the 2023 SPIE Startup Challenge.
