Abstract: The present disclosure provides a multi-beam LiDAR system. The multi-beam LiDAR system includes a transmitter having an array of laser emitters. Each laser emitter is configured to emit a laser beam. The multi-beam LiDAR system also includes a receiver having an array of photodetectors. Each photodetector is configured to receive at least one return beam that is reflected by an object from one of the laser beams. The laser emitter array includes a plurality of laser emitter boards perpendicular to a horizontal plane. Each laser emitter board has a plurality of laser emitters. The plurality of laser emitters in the laser emitter array are staggered along a vertical direction. The photodetector array includes a plurality of columns of photodetectors. One of the laser emitter boards corresponds to one column of photodetectors.
