Abstract As an important optical constants of optical properties for transparent materials,the refractive index measurement of transparent plate such as glass plate is studied using Michelson interferometer, respectively, with He-Ne laser and white light as light source. Through optical path difference analysis, according to the change law of interference stripe shape and color, the experimental results are analyzed.The test results show that the method improves the disadvantages of slide instant fringe mobile number is not easy accurate counting and measuring refraction rate when the traditional interference method is used.
