Abstract

The invention relates to a multi-line laser radar. It includes: a laser emitting device, including at least two laser emitters, for emitting multiple outgoing lasers; a secondary reflector, for dividing the outgoing laser into multiple beams, and reflecting them to the vibrating mirror at a specific angle; the vibrating mirror is used The outgoing laser light reflected by the secondary reflector is reflected to the target object in the detection field of view again; the main reflector is used to receive the reflected laser light and reflect the reflected laser light to the laser detection device; wherein the reflected laser light is the reflection of the target object The laser light returned afterward; the receiving lens is used to collect the reflected laser light to the laser detection device; the laser detection device is used to receive the reflected laser light and output the detection signal; wherein, both the vibrating mirror and the main mirror rotate synchronously around the central axis. The multi-line laser radar proposed in this application can realize the two-dimensional space scanning detection of the multi-line laser radar only by rotating the galvanometer and the main reflector. Therefore, the number of devices used is greatly reduced, thereby simplifying the multi-line laser radar. structure, thereby reducing the manufacturing cost of the multi-line laser.

Description

technical field [0001] The present application relates to the technical field of laser radar, in particular to a multi-line laser radar. Background technique [0002] With the development and application of optical technology, many laser radar systems that emit laser beams to detect the position, speed, attitude, orientation, shape and other characteristic quantities of target objects have appeared one after another, and the laser radar system can be widely used in various The field of measurement, for example, the field of navigation and positioning technology, the field of engineering ranging technology, etc. [0003] At present, the laser radar system mainly uses multi-line laser radar to realize the feature scanning and measurement of target objects in all directions, and the multi-line laser radar structure often includes multiple laser transmitters and multiple corresponding laser receivers. Among them, multiple laser emitters are arranged vertically to generate multi...
