摘要为了解决手持式激光测距仪50m以上检测基准建立的问题,在50m高精度导轨上利用3个平面反射镜进行光路折叠,实现4倍光程倍增,搭建了室内200m基线。并将Leica TS15型全站仪视为检定基准,对基线长度进行标定。最后对Leica DISTOTM D510型手持式激光测距仪开展了50~200m测段的示值误差检定实验。实验结果表明: 室内基线系统的测量范围可拓宽至200m,示值误差检定结果的扩展不确定度为2.2mm(k=2),满足检定规程要求,有利于将长基线压缩至室内有限空间完成。

Abstract：In order to solve the problem of establishing the detection standard of hand-held laser rangefinder over 50m, three plane mirrors were used to fold the optical path on the 50m high-precision guide rail to realize four-times optical path multiplication, so a 200m indoor baseline was built. Then Leica TS15 total station was regarded as the verification standard to calibrate the baseline length. Finally, the indication error verification experiment of Leica DISTOTM D510 hand-held laser rangefinder in 50~200m measuring section was carried out. The experimental results show that the measurement range of the indoor baseline system can be widened to 200m, and the expanded uncertainty of indication error verification result is 2.2mm (k=2), which meets the requirements of verification regulation, and is conducive to compress the long baseline into indoor limited space.

Key words： metrology virtual length baseline hand-held laser rangefinder plane mirror;total station light path multiplication measuremend method
