Problems solved by technology

The transmitting circuit device of the laser laser is relatively complex and the volume is relatively large, so it is impossible to stack enough quantities in a small range. The number of laser lines per unit range, that is, the stacking number of laser transmitters, affects the vertical resolution of multi-line laser radar. important factor of , so the vertical resolution of the multi-line lidar in the prior art is still low
[0004] It can be seen that the existing multi-line lidar is bulky and the vertical resolution is not high

Abstract

The embodiment of the invention discloses a multi-line laser radar and a multi-line laser radar control method. The multi-line laser radar comprises a laser emitter for emitting a laser, a compression shaping unit for coupling the emitted laser into a transmitting end fiber, the transmitting end fiber for leading transmission laser to a transmitting end optical collimating unit, and the transmitting end optical collimating unit for collimating the emitted laser light into parallel light. Therefore, the vertical resolution of the multi-line laser radar can be improved.

Description

technical field [0001] The invention relates to the detection field, in particular to a multi-line laser radar and a multi-line 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] Multi-line laser radar is a kind of laser radar, which emits laser light through a semiconductor laser transmitter and detects the echo light signal. Multi-line laser radar includes multiple laser transmitters, and each laser transmitter can measure a distance. The transmitting circuit device of the laser laser ...
