Abstract
A solid-state LIDAR system includes a plurality of lasers, each generating an optical beam having a FOV when energized. A plurality of detectors is positioned in an optical path of the optical beams generated by the plurality of lasers. A FOV of at least one of the plurality of optical beams generated by the plurality of lasers overlaps a FOV of at least two of the plurality of detectors. A controller is configured to generate bias signals at a plurality of laser control outputs that energize a selected group of the plurality of lasers in a predetermined time sequence and is configured to detect a predetermined sequence of detector signals generated by the plurality of detectors.
