Abstract
A lidar system includes one or more light sources configured to emit light pulses, a scanner configured to direct the emitted light pulses as beams along one or more scan directions to illuminate, for each orientation of the scanner with each of the plurality of beams, a respective light-source field of view corresponding to a respective pixel, and a receiver configured to detect the light pulses scattered by one or more remote targets. The receiver includes a first, second, and third detectors to detect light pulses associated with respective beams. Each detector has a separate detector field of view within which the detector receives scattered light. A spatial separation between the first detector and the second detector is greater than a spatial separation between the second detector and the third detector.
