摘　　要：根据理想退偏器的米勒矩阵形式,分析讨论了不同组合的复合波片的米勒矩阵.得出了以下结论:让两波片以不同的角速度绕光线为轴旋转,当复合波片为一个1/4波片和一个1/2波片组合时,只要它们的角速度满足一定的比例时,可以组合成一个比较理想的退偏器;当复合波片为两个1/4波片组合或为两个1/2波片组合时无论怎样旋转都不能组合成理想退偏效.这些理论结果对复合波片退偏器的设计具有好的参考价值.According to Mueller matrix of ideal depolarization, this paper discussed the Mueller matrix of different combinations wave-plate. We drew the following conclusions： Let the two wave-plates rotate around the light in different angular velocity respectly, when the combination wave- plate composited by a 1/4 wave-plate and a 1/ 2 wave-plate, if they meet the angular velocity of a certain proportion, it can be combined into an ideal depolarization; when the combination wave-plate composited by two 1/4 wave-plates or composited by two 1/2 wave-plates, no matter how rotation it can not form an ideal depolarization. These theoretical results offer a good reference value for design combination wave-plate depolarization.
