摘要

The length of calibration is related to the national economy and people’s livelihood. The traditional calibration of length value was sent the uncalibrated instrument to the laboratory, and the intrinsic error of the tested instrument was obtained in the laboratory. However, calibrating the instrument on the site produced additional errors. In this article, a remote calibration method of length measurement based on optical fiber information transmission followed by a proof of principle system was studied to reduce the additional error. The 1.0-level displacement guide rail was calibrated according to this method. The results showed that the relative error of guide rail displacement under different lengths was within 0.6%. The calibration results meet the actual standards of the guide rail. This optical method is a good candidate for remote calibration.
