Abstract: Disclosed herein are techniques for light beam scanning in a light detection and ranging (LIDAR) system. The LIDAR system includes a beam shaping subsystem configured to generate an illumination pattern elongated in a first direction, and a scanning subsystem configured to direct the elongated illumination pattern towards a plurality of positions along a second direction different from the first direction. The LIDAR system further includes a sensor configured to generate a detection signal in response to detecting light reflected by a target object illuminated by the elongated illumination pattern, and a processor configured to determine a characteristic of the target object based on the detection signal.
