Abstract

During the development of LiDAR for bathymetry, in order to ensure that the LiDAR optical system can be used properly, it is necessary to adjust the coaxial of multiple channel optical paths to minimize the loss of light energy and ensure that LiDAR can achieve normal bathymetry data acquisition. In this paper, a method of installing and adjusting LiDAR optical system is proposed. Integrated design of support platform is adopted in the structure, a scientific and reasonable mounting sequence is proposed, and multi-optical axis parallelism calibrator is used to realize the optical path coaxial of the receiving system and the transmitting system. The experiment verifies that the installed and completed LiDAR can achieve normal bathymetry.
