应用光学螺状相液晶旋光性旋光色散螺距双折射率 applied optics cholesteric liquid crystal rotation rotatory dispertion screwpitch birefringence

摘要

利用旋光理论模拟了一种用于螺状相液晶显示器(CH-LCD)的螺状相液晶的旋光率与入射波长、螺距的关系, 并从理论上给予定量分析;用磁光调制倍频法测试了这种螺状相液晶旋光率随温度变化的规律, 并利用所测的旋光率的值计算得出这种螺状相液晶的螺距、折射率、及双折射率随温度变化的规律;对模拟结果给予了实验验证。

Abstract

The relationship between specific rotation of one kind cholesteric liquid crystal for CH-LCD and incidence wavelength, screw-pitch is simulated with the general cholesteric liquid crystal optical rotation theory and analyzed quantitatively. The specific rotation-temperature characteristic of this kind cholesteric liquid crystal is measured by means of magneto-optic modulate frequency multiplication, and the variations of screwpitch, refractive index and birefringence with temperature of this kind cholesteric liquid crystal' are simulated by using its experimental specific rotation values. The simulated results are validated by experiment finally.
