Lidar device and operation method therefor

Abstract

Disclosed in an embodiment is a LiDAR device, comprising: an output unit that outputs an optical signal; a distribution unit that distributes the optical signal into a first optical signal and a second optical signal; a receiving unit that receives a third optical signal, which is reflection light of the first optical signal on an object; an interference unit in which interference between the second optical signal and the third optical signal occurs; a detection unit that detects a fourth optical signal, which is interference light generated by means of interference between the second optical signal and the third optical signal, or a fifth optical signal, which is noise; and a depth information generation unit that generates depth information and speed information for an observation target on the basis of the optical signals, wherein the distribution unit adjusts the distribution ratio of the first optical signal and the second optical signal.
