JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]A light sensor developed by the University of Texas at Austin (UT Austin) and the University of Virginia is able to amplify weak signals from far away with greater accuracy than current technology, giving autonomous vehicles a fuller picture of what’s happening on the road. The detector is able to amplify weak signals by drastically reducing noise associated with the detection process. Excessive noise causes systems to miss signals, which in the case of autonomous vehicle applications, can put passengers at risk. “Autonomous vehicles send out laser signals that bounce...Read full articleRelated content from Photonics MediaArticlesHesai Group Charges Forward with IPO Pricing: Week in Brief: 02/10/23Lidar technology company Hesai Group announced the pricing of its initial public offering of 10 million American Depositary Shares (ADS), at $19 per ADS, for a total offering size of $190 million....Photonics.com 2/10/2023Integrated Photonic Quantum Sensing Takes Aim at Climate ResearchA NASA-funded collaboration will focus on advancing quantum sensing technology to enable new understanding of Earth and the effects of climate change.
