제1 평면에 배열된 도파관(waveguide) 어레이를 갖는 LIDAR 시스템을 포함하는 장치가 제공된다. 도파관 어레이는 각각의 빔이 어레이 내 각각의 도파관으로부터 송신되는 복수의 빔을 생성하도록 구성된다. 또한, 장치는 복수의 빔을 제1 평면에서 각도 확산(angular spread)을 갖는 콜리메이트된 빔들의 팬(fan of collimated beams)으로 만들도록 구성된 콜리메이터(collimator)를 포함한다. 추가로, 장치는 제1 평면과 상이한 제2 평면에서 팬의 방향을 조정하도록 구성된 폴리곤(plolygon) 스캐너를 포함한다. 장치를 사용하는 방법이 또한 제공된다.
An autonomous vehicle includes a LIDAR system that includes a waveguide array, a collimator configured to receive a plurality of beams from the waveguide array and output a plurality of collimated beams, and a scanner configured to adjust a direction of the plurality of collimated beams. The vehicle also includes one or more processors configured to determine a range to an object based on a return signal received from reflection or scattering of the plurality of collimated beams by the object and to control operation of at least one of a steering system or the braking system based on the range.
