Abstract: The present disclosure relates to a stray light suppression device for bathymetric LiDAR onboard unmanned shipborne, belonging to the technical field of LiDAR water depth detection, particularly to a stray light suppression device for bathymetric LiDAR onboard unmanned shipborne. The device comprises an optical system component, a first objective lens barrel, a second objective lens barrel, a spectroscope barrel, a first eyepiece barrel a, a first eyepiece barrel b, a second eyepiece barrel a, a second eyepiece barrel b, a PMT detector a, a PMT detector b and a spectroscope supporting structure. Stray light suppression of an optical system with minimal field-of-view is realized, and stray light propagated by first-order, second-order and third-order scattered light paths is suppressed, so that a water depth detection capability of the bathymetric LiDAR onboard unmanned shipborne is improved and a dynamic detection range is expanded.
