应用重整化透射椭圆光度术（RTE），对具有相对高预倾角的扭曲向列单元的情况下的指向矢轮廓进行了评估。为了确定指向矢分布，我们提出了一种确定四个单元参数的新技术，即单元间隙 d、预倾角 θp、指向矢排列的扭转角 φt 以及偏振器轴与入射液晶指向矢之间的角度 φi。迄今为止，已经提出了几种测量扭曲向列（TN）单元平均倾斜角的方法，但我们同时确定四个单元参数的方法被认为在液晶显示器的评估中非常有效。
Applying renormalized transmission ellipsometry (RTE), the evaluation of a director profile in the case of a twisted nematic cell with a relatively high pretilt angle was performed. To determine the director profile, we proposed a novel technique for determining four cell parameters, namely, the cell gap d, the pretilt angle θp, the twist angle of the director alignment φt, and the angle between the axis of the polarizer and the entrance liquid crystal director φi. To date, several methods of measuring the average tilt angle of a twisted nematic (TN) cell have been proposed, but our method of simultaneously determining the four cell parameters is considered to be quite effective in the evaluation of liquid crystal displays.
