The matrix research of multiplex depolarizers

In order to find an effectual method of polychromatic light depolarizer and the development of polarization detecting technology,based on wave plate and revolver,the multiplex depolarizer effect on polychromatic light was analyzed by means of Stokes vector and Mueller matrix,the matrix presentation of Stokes vector was obtained.Then the depolarizing mechanism of polychromatic light was represented.The effect of polarized direction of the polarized light and rotation angle of revolver on depolarization was discussed through detailed calculation.The obtained results are useful for design and study about depolarizer device.
