"Revolutionary Single-Photon Raman Lidar Unleashes Underwater Potential"

Originally Published 2 years ago — by Phys.org

Researchers have developed a compact single-photon Raman lidar system that can operate underwater and remotely distinguish various substances. The system demonstrated its capability by detecting varying thicknesses of gasoline oil up to 12 meters away in a submerged quartz cell. This technology could be valuable for monitoring oil spills, detecting leaks in underwater oil pipelines, exploring oceanic resources, and analyzing underwater bubble types and sediment types such as coral reefs.

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

Originally Published 2 years ago — by Phys.org

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.
