Title:
LASER RADAR, TRANSMITTING MODULE THEREOF, RECEIVING MODULE THEREOF AND DETECTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/042079
Kind Code:
A1
Abstract:
A laser radar (10), a transmitting module (11) thereof, a receiving module (12) thereof and a detection method therefor. The transmitting module (11) of the laser radar (10) comprises a plurality of laser devices (111-11n), wherein the light emission wavelengths of the laser devices (111-11n) comprise a first wavelength and a second wavelength, and the laser devices (111-11n) that are adapted for simultaneously emitting light have different light emission wavelengths. The receiving module (12) of the laser radar (10) comprises a plurality of detectors (121-12m), wherein each detector (121-12m) is adapted for receiving an echo beam formed by a target object (1x) reflecting a laser beam that is emitted by a corresponding laser device (111-11n) in the transmitting module (11). The capability to resist interference between a plurality of detectors (121-12m) can be improved, thereby effectively guaranteeing the signal receiving performance of the laser radar (10).
