Title:
LIDAR, LASER, LASER EMISSION PANEL ASSEMBLY, AND PACKAGING METHOD FOR LASER
Document Type and Number:
WIPO Patent Application WO/2019/233499
Kind Code:
A2
Abstract:
Provided is a lidar. The lidar comprises a rotor, a laser emission system and a receiving system. The rotor has an emission chamber and a receiving chamber separate from one another. The laser emission system is arranged inside of the emission chamber and the receiving system is arranged inside of the receiving chamber. The laser emission system comprises a laser support. The laser support is used for fixing at least one laser emission panel. In the lidar of the present invention, the arrangement of the laser emission panel on the laser support works in conjunction with the arrangement of the laser emitter to readily allow for lidars to have a higher number of beams. The laser array utilizes a non-uniform distribution such that a low number of beams can achieve a high vertical resolution. The rotor is provided with a tertiary counterweight structure, such that the adjustment of counterweight can at the same time achieve better heat dissipation and lighter weight for the lidar.
