Abstract

The embodiment of the invention discloses a laser radar and a laser radar control method. The laser radar comprises a laser emitter used for emitting emission laser, a two-dimensional vibration lens used for changing light path direction of the emission laser in the vertical and horizontal directions, and a half-transparent and half-reflecting mirror used for allowing the emission laser from the laser emitter to penetrate through the two-dimensional vibration lens. According to the invention, cost of the laser radar can be reduced and vertical resolution of the laser radar is improved.

Description

technical field [0001] The invention relates to the detection field, in particular to a laser radar and a laser radar control method. Background technique [0002] Lidar is a radar system that emits laser beams to detect the position, speed and other characteristic quantities of the target. Its working principle is to first transmit the detection laser beam to the target, and then compare the received signal reflected from the target with the transmitted signal. After proper processing, the relevant information of the target can be obtained, such as target distance, azimuth, height, speed, attitude, and even shape and other parameters. [0003] For the laser radar in the prior art, if it is to realize three-dimensional scanning, that is, to realize scanning in a range of 360, multiple laser emitters are required. The cost of the laser emitter used in the lidar is high, so the cost of the lidar using multiple laser emitters in the prior art is also high. Contents of the in...
