Title:
STRAY LIGHT SUPPRESSION DEVICE FOR UNMANNED SHIP-BORNE WATER DEPTH MEASUREMENT LIDAR
Document Type and Number:
WIPO Patent Application WO/2023/241724
Kind Code:
A1
Abstract:
A stray light suppression device for an unmanned ship-borne water depth measurement LiDAR, belonging to the technical field of LiDAR water depth measurement. The device comprises a first objective lens barrel (1), a second objective lens barrel (2), a spectroscope barrel (3), a first eyepiece barrel a (4), a first eyepiece barrel b (5), a second eyepiece barrel a (6), a second eyepiece barrel b (7), a PMT detector a (8), a PMT detector b (9) and a spectroscope supporting structure (10). The device achieves stray light suppression of an optical system having an extremely small field angle and effectively suppresses the stray light propagated by first-order, second-order and third-order scattered light paths, thereby improving the water depth measurement capability and expanding the dynamic measurement range of an unmanned ship-borne water depth measurement LiDAR.
