LIDAR(light detection and ranging) 시스템은 반도체 기반, 및 반도체 기판에 배치된 하나 이상의 광 컴포넌트들을 포함한다. 하나 이상의 광 컴포넌트들은 레이저 광원으로부터 광 빔을 수신하고 - 광 빔은 LO(local oscillator)신호와 연관됨 -, 광 빔을 제1 분할 광 빔 및 제2 분할 광 빔으로 분할하고, 제1 분할 광 빔 및 제2 분할 광 빔을 광 장치로 송신하고, 제1 분할 광 빔과 연관된 제1 반사 빔 및 제2 분할 광 빔과 연관된 제2 반사 빔을 광 장치로부터 수신하고, 제1 반사 빔을 LO 신호와 페어링하고, 및 제2 반사 빔을 LO 신호와 페어링하도록 구성된다.
A system and method for combining multiple functions of a light detection and ranging (LIDAR) system includes receiving a second optical beam generated by the laser source or a second laser source, wherein the second optical beam is associated with a second local oscillator (LO); splitting the second optical beam into a third split optical beam and a fourth split optical beam; transmitting, to the optical device, the third split optical beam and the fourth split optical beam; receiving, from the optical device, a third reflected beam that is associated with the third split optical beam and a fourth reflected beam that is associated with the fourth split optical beam; and pairing the third reflected beam with the second LO signal and the fourth reflected beam with the second LO signal.
