According to one embodiment of the present invention, disclosed is a distance measuring head. The distance measuring head comprises: a reflective surface generating a reference pulse by reflecting a part of laser pulses transmitted from a laser light source unit to the laser light source unit; a light distributor distributing a measurement pulse received from a measurement target; and a location sensor receiving the measurement pulse distributed from the light distributor. The measurement pulse is that the laser pulse is reflected from the measurement target. A distance between the reflective surface and the measurement target is measured based on a time difference that the measurement pulse which passed the light distributor and the reference pulse reach the laser light source unit. 본 발명의 일 실시예에 따르면, 레이저 광원부로부터 전송되는 레이저 펄스 중 일부를 상기 레이저 광원부측으로 반사시켜 기준 펄스를 생성하는 반사면; 측정대상으로부터 수신한 측정 펄스를 분배하는 광분배기; 및 상기 광분배기에서 분배된 측정 펄스를 수신하는 위치센서;를 포함하고, 상기 측정 펄스는 상기 레이저 펄스가 측정대상에서 반사된 것이고, 상기 광분배기를 통과한 측정 펄스와 상기 기준 펄스가 상기 레이저 광원부에 도달하는 시간차에 기초하여 상기 반사면과 측정대상 사이의 거리가 측정되는 것을 특징으로 하는 거리측정 헤드를 개시한다.
