摘　　要：为深入了解液晶的磁旋光特性,利用矩阵方法分析研究了液晶的旋光效应,导出了液晶旋光的矩阵表示．通过测量磁场作用下向列型液晶的旋光角及透射比,研究了液晶的磁旋光特性．详细分析了磁场对液晶分子轴旋转和透射比的影响,做出了液晶分子轴旋转角和透射比与磁场强度关系的曲线．通过改变磁场方向进行实验测试,发现液晶的旋光方向与垂直入射液晶盒的磁场方向无关．In order to master the magnetic optical rotation characteristic of liquid crystal, the matrix method is employed to analyze the optical rotation effect of liquid crystal, and the matrix presentation of optical rotation of liquid crystal is given. The magnetic optical rotation characteristic of liquid crystal is studied by testing rotation angle and transmission of liquid crystal. Influences of magnetic field on rotation angle of molecular axis and transmission of liquid crystal are analyzed. Relation curves of rotation angle and transmission of liquid crystal with magnetic field are protracted. By altering the direction of magnetic field, the rotation light of liquid crystal is tested, and a conclusion is gained that the optical rotation direction of liquid crystal is independent of the direction of magnetic field.
