LIDAR 시스템은 복수의 제1 이미터를 포함하는 제1 광 송신기를 포함하고, 제1 이미터들의 각각은 타겟 범위에서 FOV를 갖는 광학 빔을 생성하도록 위치한다. 제2 광 송신기는 복수의 제2 이미터를 포함하고, 제2 이미터들의 각각은 타겟 범위에서 FOV를 갖는 광학 빔을 생성하도록 위치한다. 제1 및 제2 광 송신기는, 광학 빔들 중 적어도 일부의 FOV가 타겟 범위에서 중첩되도록 위치한다. 제어기는, 타겟 범위에서 중첩되는 FOV를 갖는 광학 빔들을 생성하는 복수의 제1 이미터와 복수의 제2 이미터 중 선택된 이미터들로의 에너지 공급을 제어하는 제어 신호를 생성하고, 타겟 범위에서 대상으로부터 반사되는 광학 빔들을 검출하도록 복수의 광 검출기 중 선택된 광 검출기들을 활성화하여 제어 신호를 생성한다.

    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.
