Abstract: A method for manufacturing a LiDAR device is proposed. The method may include providing a LiDAR module including a laser emitting module and a laser detecting module to a target region. The method may also include adjusting, on the basis of first detecting data obtained from the laser detecting module, a relative position of a detecting optic module with respect to the laser detecting module. The method may further include adjusting, on the basis of image data obtained from at least one image sensor, a relative position of an emitting optic module with respect to the laser emitting module.

Abstract: A light detection and ranging (LiDAR) device comprising: a laser emitting chip configured to emit laser, a laser detecting chip configured to detect laser, an emitting optic module configured to guide laser generated from the laser emitting chip to the outside of the LiDAR device, a detecting optic module configured to guide laser received from the outside of the LiDAR device to the laser detecting chip, an emitting optic holder located between the laser emitting chip and the emitting optic module, and an at least one emitting optic fixer located between the emitting optic holder and the emitting optic module, wherein the at least one emitting optic fixer is configured to fix a relative position between the laser emitting chip and the emitting optic module.
