摘要

．提出了一种测量向列液晶层在旋转磁场和变电场作用下的交叉偏振光透射率的方法。考虑了向列液晶在这种场中的行为。设计了实现该方法的实验装置，在安装在旋转平台上的两个NdFeB(钕-铁-硼)圆盘之间产生旋转磁场。给出了LC-1289光传输的测量结果和磁盘间磁场均匀性的估计。

A METHOD FOR INVESTIGATING THE BEHAVIOR OF LIQUID CRYSTALS IN VARIABLE ELECTROMAGNETIC FIELDS

. We present a method for measuring optical transmission in crossed polarizers of a nematic liquid crystal layer under the action of rotating magnetic and variable electric fields. The behavior of a nematic liquid crystal in such fields is considered. An experimental setup implementing the method is designed, where the rotating magnetic field is generated between two NdFeB (neodymium–ferrum–borum) disks installed on a rotating platform. The measurement results of the optical transmission in LC-1289 and the estimates of homogeneity of the magnetic field between the disks are presented.
