Abstract In order to effectively carry out indoor verification of long-distance photoelectric distance measuring instruments, an indoor virtual baseline field was built based on the principle of folding optical path with a group of plane mirrors. The measurement error of the baseline system was analyzed. Considering the adjustment accuracy of various errors, the analysis results were applied to the actual optical path adjustment process. Through the analysis, the errors which have more significant effect on the baseline length were obtained, and they were controlled and adjusted to improve the adjustment accuracy of the parallelism of the measuring optical path. Finally, a dual frequency laser interferometer was used to provide reference length value to carry out the verification experiment. The experimental results show that double optical path multiplication can be achieved by optical path folding method, and the baseline system has high accuracy and can be used for continuous measurement, effectively solving the technical problems of low detection efficiency and poor repeatability in the process of indoor baseline establishment.
