摘要

建立了一种测量垂直向列液晶预倾斜角和胞隙的实验装置。这种基于旋转方法的设置经过了修改，以便同时测量反射单元中的高预倾角和单元间隙。预倾角的确定是通过找到最大和最小透射率的旋转角度来实现的。

Measurement of Pretilt Angle and Cell Gap in Reflective Vertically Aligned Nematics

An experimental setup to measure the pretilt angle and cell gap in reflective VAN (vertically aligned nematic liquid crystals) has been developed. This setup, based on the rotation method, has been modified in order to measure simultaneously high pretilt angles in reflective cells along with the cell gap. The determination of the pretilt angle is achieved by finding the rotation angle for maximum and minimum transmittances.
