Measuring method of relief depth and refractive index variation in a holographic phase medium
The paper presents a method of measuring relief depth and refractive index variation in holographic phase media. By the method an reflection interference microscope and a micro-computer with a CCD camera are used in testing, and can obtain highly precise data of them. In the paper, the testing error is analysed, the optimum conditions which make the measuring system keep its highest accuracy are given.
