Abstract
A laser radar device comprises a laser projecting system and a laser radar detecting system. The laser projecting system comprises a laser diode; and a light source orientation adjustment unit comprising a collimating lens and a Powell lens to modulate the angle at which the first incident laser beam is projected onto an object. The laser radar detecting system comprises at least two laser radar detection units disposed in the horizontal direction and vertical direction of the object, respectively. The laser radar detection units each comprise a wedge-shaped lens, an aspherical lens system and an optical detector. By designing optical parameters of the wedge-shaped lens and stacking the laser radar detection units in the horizontal direction and vertical direction, it is feasible to facilitate overall device manufacturing and processing, meet R&D needs, and adjust an optical system in its entirety easily.
