Abstract

The invention relates to multi-line laser radar. The multi-line laser comprises a laser emitter, a light shaping device, a secondary mirror, a primary mirror, a receiving lens and a laser detector, wherein the laser emitter is used for emitting outgoing laser; the light shaping device is used for expanding the coverage of the outgoing laser; the secondary mirror is used for reflecting the laser light emitted through the light shaping device onto the primary mirror; the primary mirror is used for reflecting the laser light reflected by the secondary mirror onto a target object in a detection field of view, receiving the reflected laser light and reflecting the reflected laser light to the laser detector; the reflected laser light is laser that returns after the outgoing laser is reflected by the target object; the receiving lens is used for collecting the reflected laser light onto the laser detector; the laser detector is used for receiving the reflected laser light and outputting detection signals; and the laser emitter, the secondary mirror, the primary mirror, the receiving lens and the laser detector synchronously rotate around a central axis. The multi-line laser radar disclosed in the application realizes single-shot and multi-receiving laser detection, and is simple in structure and low in cost.

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 in the multi-line laser radar structure, it often includes multiple laser emitters and multiple corresponding laser detectors. Among them, multiple laser emitters are arranged vertically to generate mu...
