1. A light detection and ranging (LiDAR) system, comprising:
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
a first 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.
