Abstract

The feasibility of an overwater light-sheet Scheimpflug lidar system for underwater three-dimensional (3D) profiling is considered. Corrections for the refraction at the air-water interface are proposed. Applications for profiling marine ecosystems are explored in distance up to several meters, and millimeter precision is accomplished. The experimental results demonstrate that our system is suitable for underwater 3D profiling and has great potential in marine biological detection.
