Robust real-time 3D imaging of moving scenes through atmospheric obscurant using single-photon LiDAR

Abstract Recently, time-of-flight LiDAR using the single-photon detection approach has emerged as a potential solution for three-dimensional imaging in challenging measurement scenarios, such as over distances of many kilometres. The high sensitivity and picosecond timing resolution afforded by sing...
