手持式激光测距仪是利用激光对目标的距离进行准确测定的仪器。激光测距仪在工作时向目标射出一束很细的激光束，由光电元件接收目标反射的激光束，计时器测定激光束从发射到接收的时间，计算出从观测者到目标的距离。能进行距离、面积、体积的测量， 在室内和室外都能进行测量。
该手持式激光测距仪系统具有体积小、重量轻、测程远、操作简便、测距误差小、密封性能好、可靠性高等特点。
The hand-held laser range finder system had such characteristics as small size, light weight, long measurement range, easy operation, ranging error, sealing performance and high reliability.
此系统结构简单，体积小，可靠性高，非常适合高性能手持式脉冲激光测距仪。
The time measurement system is adapted extraordinarily to high performance portable pulsed laser rangefinder for its compactness, simple structure, and high reliability.
