    Abstract: A light detection and ranging (LIDAR) system for a vehicle, includes a laser source configured to generate light signals, a transceiver, and a fiber array coupled to the transceiver and including a plurality of output channels. The transceiver is configured to receive one or more light signals from the laser source through a first group of output channels of the fiber array, receive one or more local oscillator (LO) signals through a second group of output channels of the fiber array, transmit the one or more light signals into an environment of the vehicle, receive a first returned light reflected from one or more objects in the environment, and output the first returned light and a first LO signal of the one or more LO signals.

    Abstract: 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.
