全光纤电流互感器的偏振误差研究

Study of Polarization Errors of All Fiber Optical Current Transformers

借助琼斯矩阵对全光纤电流互感器的偏振误差进行了研究.通过建立光纤电流互感器各主要光学器件的琼斯矩阵表达式,推出了反射式光纤电流互感器的干涉表达式,并分析了各光学器件主要参量对其测量准确度的影响.

Using the Jones Matrices formalism, the polarization errors of the FOCT was studied. Through building the expression of the main optical parts of the FOCT and the expression of interference, the precision which is affected by the parameters of the main optical parts was analyzed.
