Abstract
A LiDAR system is provided. The LiDAR system comprises a plurality of transmitter channels and a plurality of receiver channels. The plurality of transmitter channels are configured to transmit a plurality of transmission light beams to a field-of-view at a plurality of different transmission angles, which are then scanned to cover the entire field-of-view. The LiDAR system further comprises a collection lens disposed to receive and redirect return light obtained based on the plurality of transmission light beams illuminating one or more objects within the field-of-view. The LiDAR system further comprises a plurality of receiver channels optically coupled to the collection lens. Each of the receiver channels is optically aligned based on a transmission angle of a corresponding transmission light beam. The LiDAR system further comprises a plurality of detector assemblies optically coupled to the plurality of receiver channels.
