Title:
LASER RADAR
Document Type and Number:
WIPO Patent Application WO/2020/143542
Kind Code:
A1
Abstract:
A laser radar, comprising a laser emitting module, a light splitting module, a scanning module, and a receiving module, the laser emitting module being used for emitting a pulse laser beam; the light splitting module is used for splitting the pulse laser beam into N incident light beams and transmitting same to the scanning module, and N≥2; the scanning module is used for reflecting the N incident light beams to a three dimensional space and is used for receiving and reflecting N echo light beams of the N incident light beams after being reflected by a target to be measured in the three dimensional space; and the receiving module is used for receiving and processing the N echo light beams; the light splitting module and the scanning module correspondingly form N sub-scanning fields of view, the N sub-scanning fields of view, by means of field of view splicing, constituting the total field of view of the laser radar. The laser radar employs the light splitting module in order to use at least N light sources whilst satisfying the scanning field of view of the laser radar, reducing the cost of the laser radar, reducing the internal heat generation, and decreasing the volume of the laser radar.
