Zusammenfassung:	Disclosed are a lidar device and an operating method thereof. The operation method includes the steps of: irradiating a laser light toward an object; outputting a laser reflection light signal by detecting the laser light reflected from the object; measuring a pulse width corresponding to a period in which the laser reflection light signal is saturated from the laser reflection light signal and changing at least one of laser light intensity to be irradiated by the laser light irradiator or a gain of an amplifier according to the analyzed pulse width; and controlling the laser light irradiator to irradiate an adjusted laser light corresponding to the changing. 라이다 장치 및 그 동작 방법은, 대상체를 향하여 레이저 광을 조사하고, 대상체로부터 반사된 레이저 광을 검출함으로써 레이저 반사광 신호를 출력하고, 레이저 반사광 신호가 포화된 구간에 대응하는 펄스 폭을 측정하여 레이저 광 조사부에 의해 조사될 레이저 광 세기 및 증폭기의 이득 중 적어도 하나를 변경하고, 레이저 광 조사부로부터 변경에 대응하는 조정 레이저 광이 조사되도록 제어한다.
