Abstract :
Based on our newly-designed series of targets at intervals, the range-gated phenomenon of underwater lidar imaging is much clarified. In extremely turbid water with attenuation 2.3/m, targets 1.5 m apart in distance cannot be observed by the non-gated camera at all, but its image could be recorded by our UWLI system.
