Abstract

A LiDAR system includes an optical source to emit an optical beam, an optical window to reflect a first portion of the optical beam to generate an LO signal, and an optical scanner to transmit a second portion of the optical beam to a target to scan the target to generate a target return signal. The LiDAR system includes a birefringent crystal plate to transmit the LO signal and the target return signal to a PD and shift the LO signal and the target return signal by different displacements to increase a percentage of an overlap of the LO signal and the target return signal on a detection plane of the PD. The LiDAR system includes the PD to mix the target return signal with the LO signal on the detection plane of the PD to generate a heterodyne signal to extract range and velocity information of the target.
