| Abstract: | A method of measuring the phase modulation characteristics of filter spatial light modulator by using correlation analysis the data of one-dimensional interference fringe in the Vanderlugt correlator is suggested.The in-situ measurement principle,set-up and processing of the phase modulation characteristic of XGA2L11 are presented.The experiment results are verified by using Vanderlugt correlator,it shows that the method can be used to measure phase modulation characteristics of spatial light modulator in accuracy and simplicity. |
