Abstract
A LIDAR system includes a plurality of lasers that generate an optical beam having a FOV. A plurality of detectors are positioned where 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. The lens system collimates and projects the optical beams generated by the plurality of lasers. An actuator is coupled to at least one of the plurality of lasers and the lens system to cause relative motion between the plurality of lasers and the lens system in a direction that is orthogonal to an optical axis of the lens system so as to cause relative motion between the FOVs of the optical beams generated by the plurality of lasers and the FOVs of the detectors.
