Abstract
The paper proposes a method of measuring relief depth and refractive index variation which distribute in a holographic phase grating. By this method an interference microscope and a microcomputer with a CCD camera are used in measuring and can obtain highly precise data. In the paper, an example of measuring DCG grating is presented, the errors of these data are analyzed and optimum conditions which make a measurement system keep its highest accuracy are given.
