Zusammenfassung:	A lidar device having an improved signal-to-noise ratio is disclosed. The disclosed lidar device may include: a light source for generating light having a predetermined wavelength; an optical transmitter for emitting the light generated by the light source to the outside; an optical receiver for receiving light coming from outside; a resonance type photodetector for selectively amplifying and detecting light having the same wavelength as that of the light generated by the light source among the light received by the optical receiver; and a processor for controlling operations of the light source and the resonance type photodetector. 향상된 신호대 잡음비을 갖는 라이다 장치가 개시된다. 개시된 라이다 장치는, 소정의 파장을 갖는 광을 발생시키는 광원; 상기 광원에서 발생한 광을 외부에 방출하는 광 송신기; 외부로부터 오는 광을 수신하는 광 수신기; 상기 광 수신기에서 수신한 광 중에서 상기 광원에서 발생한 광의 파장과 동일한 파장의 광을 선택적으로 증폭시켜 검출하는 공진형 광 검출기; 및 상기 광원 및 상기 공진형 광 검출기의 동작을 제어하는 프로세서;를 포함할 수 있다.
