Abstract
A light detection and ranging (LIDAR) system includes a laser, a transceiver, and one or more optics. The laser source is configured to generate a beam. The transceiver is configured to transmit the beam as a transmit signal through a transmission waveguide and to receive a return signal reflected by an object through a receiving waveguide. The one or more optics are external to the transceiver and configured to optically change a distance between the transmit signal and the return signal by displacing one of the transmit signal or the return signal.
