| Abstract: | This paper describes the principle of the interferemetry based on the spatial phase modulation technique with the wave optic theory. It also describes the interfermenter based on the spatial phase modulation technique, which can be used to measure the microdisplacement, and suggests the two measuring ways of the interferemeter that are the mono stripe way and the dual stripe way. At last, the measuring result of the microdisplacemen is given. |
