Real-time 3D imaging achieved by quantum lidar prototype underwater.

Researchers have developed a lidar system that uses quantum detection technology to acquire 3D images while submerged underwater. The system uses single-photon detection, which allows high penetration and works even in low-light conditions. The technology could be useful for inspecting underwater installations, monitoring or surveying submerged archaeology sites, and for security and defense applications. The researchers are now working to reduce the size of the system so that it could be integrated into an underwater vehicle.
