Birefringent crystals are extensively used to manipulate polarized light. The generalized transfer matrix developed allows efficient calculation of the full polarization state of light transmitted through and reflected by a stack of arbitrarily many discrete layers of isotropic and birefringent materials at any frequency and angle of incidence. The matrix of a uniaxial birefringent crystal with arbitrary rotation is calculated, along with its reduction to the matrix of an isotropic medium. This method is of great practical importance where tight control of systematic effects is needed in optical systems employing birefringent crystals, one example being wave plates used by cosmic microwave background polarimetry with wide field-of-view telescopes.
双折射晶体被广泛用于操控偏振光。所开发的广义传输矩阵能够高效计算在任意频率和入射角下，透过任意多各向同性和双折射材料离散层堆叠并由其反射的光的全偏振态。计算了具有任意旋转的单轴双折射晶体的矩阵，以及将其简化为各向同性介质的矩阵。在使用双折射晶体的光学系统中，当需要严格控制系统效应时，该方法具有重要的实际意义，一个例子是用于具有宽视场望远镜的宇宙微波背景偏振测量的波片。
