摘要
简述了全光纤电流互感器中λ/4光纤波片的功能,研究并得出λ/4光纤波片的制作参数,分析λ/4光纤波片在全温条件下产生的温度漂移问题,并从材料选择及温度补偿技术两个方面探讨了减小温度漂移的方案,并通过实验验证了其可行性。
The function of λ/4 wave plate in fiber optical current transformer （FOCT） is introduced.The fabrication factors of λ/4 wave plate are studied and the temperature drift of λ/4 wave plate at all temperature conditions are analyzed.The solution which can reduce the temperature drift from material selection and temperature compensation technology is discussed.And its feasibility is verified by experiment.
