Abstract: A LIDAR system includes a first optical transmitter comprising a plurality of first emitters, where each of the plurality of first emitters is positioned to generate an optical beam with a FOV at a target range when energized. A second optical transmitter includes a plurality of second emitters, where each of the plurality of second emitters is positioned to generate an optical beam with a FOV at the target range when energized. The first and second optical transmitters are positioned relative to each other so the FOVs of at least some of the optical beams generated by the first and second optical transmitter when energized overlap at the target range. An optical receiver includes a plurality of optical detectors, where a respective one of the plurality of optical detectors is positioned to detect a respective optical beam generated by at least one of the first and second optical transmitter and reflected by a target in the FOV at the target range. A controller includes a first and second output being connected to respective control inputs of the first and second optical transmitters, and a third output being connected to a control input of the optical receiver. The controller generates control signals at the first and second outputs that control energizing select ones of the plurality of first and the plurality of second emitters that generate optical beams with the FOVs that overlap at the target range and generating a control signal at the third output that activates selected ones of the plurality of optical detectors to detect optical beams reflected from an object at the target range.
