Abstract

본 발명은 레이저를 이용하여 소정 물체와의 거리를 측정할 경우에 수신된 레이저를 처리하는 경로에서의 지연으로 인한 측정 오차를 줄일 수 있도록 하는 것이다. 본 발명은 레이저 출력부(1)가 출력하는 레이저를 레이저 수신부(2)가 직접 수신함과 아울러 거리를 측정할 물체에서 반사되는 레이저를 레이저 수신부(3)가 수신하고, 수신한 두 레이저를 동일한 지연 시간을 가지는 증폭기(4)로 증폭하여 동일한 시간 지연이 발생되게 한 후 신호 처리부(5)가 두 레이저의 시간차를 검출하여 거리를 정확하게 측정한다.The present invention is to reduce the measurement error due to the delay in the path for processing the received laser when measuring the distance to a predetermined object using a laser. According to the present invention, the laser receiver 3 directly receives the laser output from the laser output unit 1, and the laser receiver 3 receives the laser reflected from an object to measure the distance, and the two lasers received the same delay. After amplifying the amplifier 4 having a time to generate the same time delay, the signal processor 5 detects the time difference between the two lasers and accurately measures the distance.
