Description

Technical Field

[0001] The present disclosure relates to the technical field of radar performance testing, and in particular to a laser radar system with health status monitoring and control functions. Background Art

[0002] LiDAR (Light Detection and Ranging) uses lasers as light sources to remotely sense the atmosphere by detecting the echo signals generated by the interaction between lasers and the atmosphere. It possesses high-precision distance resolution capabilities. The interaction between lasers and the atmosphere produces radiation signals containing information about gas atoms, molecules, atmospheric aerosol particles, and clouds. Using appropriate inversion methods, this information can be derived from these signals.

In this embodiment, the photosensitive portion of the energy detection board 2 can receive the irradiation of the residual laser light from the laser 12.
