Abstract
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 di- rection of magnetic field.
