摘　　要：为了探索一种简单有效的复色光退偏方法以及偏光探测技术的发展,利用斯托克斯矢量和米勒矩阵分析了波片和旋转器组合对复色光的退偏效应,导出了斯托克斯矢量的具体形式,阐述了复色光的退偏机理。通过计算讨论了偏振光的偏振方向和旋转器的旋转角对退偏情况的影响。结果表明,这种退偏器其退偏效果更加理想,对退偏器的设计与研究具有一定的参考价值。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.
