Abstract
A LiDAR system includes an optical source to emit an optical beam toward a target, a partially reflective surface to generate a local oscillator (LO) signal from the optical beam, and an optical lens disposed in front of a photodetector (PD), wherein the LO signal is incident at a decenter of the optical lens to shift the LO signal at the photodetector with respect to a return signal received from the target.
