Abstract: The theory of dual linear polarization light interference is reviewed,and thus the functional relationship between the visibility and the angle of two planes of polarization in the interference picture is obtained.Based on the Michelson interferometer with optical path and with the addition of  the polarizers,the dual linear polarized light interference is realized.By adjusting the direction of polarizers plane and changing the angle,the interferance pictures in different angle are obtained.Using the CCD recorded interference pattern image,the theoretical and experimental results are compared.Analysis results indicate that the predictions of the theory are supported by experimental results qualitatively.
