A simple and highly accurate measurement method was devised for the alignment distribution of liquid crystal molecule and surface polar anchoring strength by considering the incident angle dependence of multiple interferences in the homogeneous alignment LC cell. We measured the temperature dependence of the polar anchoring strength on the surface of alignment layers and clarified that the there is a relation between the polar anchoring strength and the LC absorption layer on the surface of alignment layers.

考虑到均匀取向液晶盒中多重干涉的入射角依赖性，设计了一种简单、高精度的液晶分子取向分布和表面极性锚定强度的测量方法。我们测量了取向膜表面的极性锚定强度随温度的变化关系，并阐明了取向膜表面的极性锚定强度与液晶吸收层之间的关系。
