This ellipsometric method does not need to rotate the sample azimuthally. The physical parameters of sample are measured under various linear polarized lights through the numerical fitting to its theoretical model. In addition to the orientation of the first layer of nematic liquid crystal is considered, the total phase retardation and twist angle of twist Nematic Liquid Crystal cell are the physical parameters measured by this method.

本论文以椭圆偏极术为基础，在不需转动样本方位角的情况下，以不同偏振方向的线性偏振光入射样本，藉由出射光偏振态的变化，用数值方法拟合出样本矩阵模型参数；我们所量测的样本为扭转式液晶盒，其矩阵模型包含了三个参数：总相位延迟、扭转角及第一层液晶锚定方向。
