The present invention relates to a multi-target distance measurement system. One embodiment comprises: a plurality of light splitters; a plurality of measurement heads optically and respectively connected with one end of each of a plurality of light paths divided from the plurality of light splitters; and a distance measurer which measures a distance from each measurement head to a measurement target. The disclosed multi-target distance measurement system irradiates the measurement target with a laser pulse through each of the plurality of measurement heads. When the distance measurer receives a reference pulse and measurement pulse from each measurement head, the system calculates a distance between each measurement head and the measurement target based on a reception time difference of the reference pulse and measurement pulse of each measurement head. The multi-target distance measurement system monitors a distance change in real time with high measurement accuracy. 본 발명은 다중대상 거리측정 시스템에 관한 발명으로, 일 실시예에서, 복수개의 광분할기; 상기 복수개의 광분할기에서 분할된 복수개의 광경로의 각각의 단부에 하나씩 광학적으로 연결된 복수개의 측정헤드; 및 각 측정헤드에서 측정대상까지의 거리를 측정하는 거리측정기;를 포함하고, 상기 복수개의 측정헤드의 각각을 통해 레이저 펄스를 측정대상을 향해 조사하고, 상기 거리측정기가 각 측정헤드로부터 기준 펄스와 측정 펄스를 수신하면, 각 측정헤드의 기준 펄스와 측정 펄스의 수신 시간차에 기초하여 각 측정헤드와 측정대상 사이의 거리를 산출하도록 구성된 다중대상 거리측정 시스템을 개시한다.
