Title:
OPTICAL DEVICE AND LASER RADAR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/103823
Kind Code:
A1
Abstract:
An optical device and a laser radar system, relating to the technical field of optics. The optical device comprises a base, a laser light source connected to the base, and an optical module arranged on the base. The optical module comprises at least two optical elements; the laser light source emits a light beam towards the optical module to form a light spot; the optical device further comprises a compensation structure; the at least two optical elements are fixed to the base along a first direction by means of the compensation structure so as to compensate for the relative distance between the at least two optical elements in the optical axis direction; the first direction is a direction insensitive to the angle of divergence and the directivity index of the light spots. The compensation structure compensates for a distance change between the at least two optical elements along the optical axis direction due to high and low temperatures.
