Abstract
A light detection and ranging (LiDAR) device includes a transmitter configured to transmit a continuous wave light to an object and provide a local oscillator (LO) light corresponding to the transmitted continuous wave light; a delay circuit configured to time delay the LO light; a receiver configured to receive the continuous wave light reflected from an object; and a detection circuit configured to determine a distance from the LiDAR device to the object based on the time delayed LO light and the received continuous wave light.
