摘要

利用全漏导波技术对反扭曲向列相负性液晶盒进行了研究

通过测量液晶盒全漏波导几何结构在不同电压作用下随内角变化的反射光强

并与理论模拟进行对比和拟合来确定液晶及液晶盒的多项参数

进而探究反扭曲向列相液晶盒内部液晶指向矢分布的信息。

Abstract

Using the fully-leaky waveguide technique

the inverse twisted nematic (ITN) negative liquid crystal cell is investigated. The intensity of reflected light dependent on the internal angle through the fully-leaky liquid crystal waveguide geometry is obtained from experiment with various voltages. Compared with theoretical result

some parameters of liquid crystal material and liquid crystal cell are determined

and then the information of liquid crystal director within the liquid crystal cell is also obtained.
