Abstract

As an important length ratio measurement system, the indoor large length standard device has important scientific research value, and the laser interferometer measurement system is responsible for the data acquisition task of the indoor large length standard device. In this paper, the plane measurement and analysis of the static three-way laser interferometer measurement system are carried out. Through the Angle measurement of 100 groups of measuring planes, the results show that the plane Angle formed by the three-way laser interferometer on the surface is a wave shape, the maximum position of the Angle is 7500 mm, the Angle is 12.0204 ". It reflects that the composite guide system of indoor large length standard device is good and the cosine error of indoor large length standard device is small.
