菲涅尔反射替代反射镜在高双折射旋转光纤测试中的应用

Application of Finel reflection mirror in high birefringence rotating optical fiber test

高双折射旋转光纤是全光纤电流互感器中的一种关键材料。本文提出在评估高双折射旋转光纤的高低温性能时,使用光纤端面菲涅尔反射的方法替代在光纤端面镀膜加工反射镜,并通过实验对这一方法进行了验证。

High birefringent spun fiber is a key material in FOCT(Fiber Optic Current Transformer) system. A new method of using Fresnel reflection instead of reflecting coating method is introduced to reduce the cost when evaluating the temperature property of high birefringent spun fiber? Results indicate the equivalence of both methods?
