| 摘 要： | 讨论了迈克尔逊干涉仪补偿板的作用和补偿板角度改变量的测量方法。补偿板的转动会引起光程差的变化，产生干涉条纹数目的变化。通过测量条纹的改变数目，算出补偿板的角度改变量。文中所述方法新颖，精确度较高。

| 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. |

| Keywords: | Michelson interferometer refractive index micro-angle variational fringes |
