Abstract

One embodiment of the invention discloses a laser radar and a laser radar control method. The laser radar comprises 2N+1 laser emitters for emitting laser; a vibrating mirror for changing the opticalpath direction of the emitted laser; N is an integer and N is no less than zero. According to the embodiment, since the laser emitters are added, the scanning scope of laser radar is enlarged and therefore the scanning angle of the laser radar is increased.

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] Lidar includes mechanical lidar and solid-state lidar. Solid-state lidar can use a vibrating mirror to change a single laser beam into multiple laser beams, thereby saving costs. [0004] The frequency / scanning angle of the galvanometer used in solid-state lidar is inversely proportional to the mirror area of ​​the galvanometer, that...
