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 limited spectral sensitivity of the light sensors used. Extending NLOS imaging capabilities to the near- and mid-infrared (NIR and MIR) wavelengths could expand the application spaces for this emerging technology.
