摘要

研究了液晶的电致衍射现象，实验表明，在驱动电压适当的情况下，液晶分子会出现类似于光栅的周期性分布结构，即液晶衍射光栅。利用两个错位重叠光栅产生的不同偏振态光波的叠加解释液晶光栅的衍射过程和衍射特征，并研究了衍射图样的分布及偏振态变化的规律。

Abstract:

The electro diffraction phenomenon of liquid crystal is studied.The experiment shows that when thedriving voltage is appropriate , the liquid crystal molecules will appear a periodic distribution structure similar tothe grating,that is ,the liquid crystal diffraction grating.The diffraction process and diffraction characteristics ofiquid crystal grating are explained by the superposition of light waves with different polarization states produced by two staggered superposition gratings ,and the distribution of diffraction pattern and the change lawof polarization state are studied.

Key words: liquid crystal polarization diffraction electro-optic effect
