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
