Design method of laser radar debugging lens

The invention belongs to the field of laser radars, and relates to a design method of a laser radar debugging lens. Comprising the following steps: firstly, taking an optical detector in a laser radar receiving module as an observation object for debugging a lens; the emergent light of the optical detector passes through an optical receiving lens group in the laser radar receiving module and then is emitted in parallel. After the parallel light enters the optical condensing lens group, an amplified inverted real A 'B' image is formed on the photoelectric sensor; secondly, calculating a field angle and a focal length of a debugging lens; and finally, carrying out light path design and optimization. According to the scheme, debugging lenses suitable for different laser radars can be designed, so that the debugging lenses can effectively converge emission light spots, the light spot position of a laser emission light path is determined, and meanwhile, a receiving light path can be clearly observed.
