Nanowire Single-photon Detector Lets Machines See Through Walls
TIANJIN, China, Dec. 5, 2023 — Using a superconducting nanowire single-photon detector (SNSPD) as the light-sensing element, researchers from Tianjin University demonstrated non-line-of-sight (NLOS) imaging at two infrared (IR) wavelengths, 1560 nm and 1997 nm. NLOS systems provide the capability to see around corners and even through walls, making them valuable tools for applications ranging from endoscopy to autonomous vehicles and robotic vision. Most NLOS imaging is performed in the visible bands, due to the
