Open publisher page 0 citations

Abstract

This paper discusses the role of Compensator in Michelson interferometer and the method to measure its angle change.The rotation of Compensator can cause the change of optical pathlength,and the number of interference fringes will change simultaneously.By measuring the change of the fringe numbers,we can calculate the angle change.This method is novel and can reach higher precision.
