LIDAR DEVICE HAVING A SMART POWER MANAGEMENT SYSTEM AND AN OPERATING METHOD OF THE LIDAR DEVICE IMPLEMENTING THE SMART POWER MANAGEMENT SYSTEM

A light detection and ranging (LiDAR) device includes a laser emitting unit configured to emit laser, a laser detecting unit configured to detect laser emitted from the laser emitting unit and a controller configured to operate the LiDAR device in a first operation mode and a second operation mode in which a power consumption per unit time is lower than a power consumption per unit time of the first operation mode.
