Phys.org  August 1, 2023 Traditional active sensors like LiDAR have drawbacks that increase as they are scaled up, including signal interference and risks to people’s eye safety. A team of researchers in the US (Purdue University, Michigan State University) proposed and experimentally demonstrated heat-assisted detection and ranging (HADAR) overcoming the open challenge of ghosting and benchmark it against AI-enhanced thermal sensing. HADAR not only sees texture and depth through the darkness as if it were day but also perceives decluttered physical attributes beyond RGB or thermal vision, paving the way to fully passive and physics-aware machine perception. They developed HADAR […]
