摘　　要：针对旋光元素ε′的测量问题,通过理论分析,提出了测量旋光光纤张量介电常数矩阵中旋光元素ε′的基本原理和方法.首先从理论上推导出旋光角Ψ和ε′的关系式,再对表征光纤旋光特性的Ψ和常数V进行测量,并在此基础上对ε′进行测量,最后给出了Ψ、V和ε′的测量结果.ε′的测量对于旋光光纤的电磁场理论分析及数值计算具有重要意义.Aiming at the measurement of rotatory element ε′,a measuring principle and method about rotatory characteristic of a rotatory optical fiber are discussed.The correlation between rotatory angle Ψ and rotatory element ε′ is deduced theoretically.Some tensor dielectric coefficient of the rotatory optical fiber are measured such as Ψ,ε′ and rotatory coefficient V and the measuring results are given.In general,the measurement of rotatory element ε′ is very difficult,but that becomes very easy by means of the measuring principle and method put forward in this paper.The measument of ε′ is very important for numerical analysis and calculation of the rotatory fiber by electromagnetic theory.
