斯托克斯矢量法在全光纤电流传感器中的应用

针对目前全光纤电流传感器中光信号检测环节多是采用双路光强分析偏振度这一现状, 提出将斯托克斯矢量法应用于光纤电流传感器信号偏振度的演变分析, 在近似条件下, 推导得到基于穆勒矩阵的光纤电流传感器简化传输矩阵.从琼斯矢量法和实验结果的比较可知, 斯托克斯矢量法与琼斯矢量法的模拟效果十分接近, 此外它还具有传输矩阵中不存在复数、容易简化为稀疏矩阵以及最终偏振度只需计算总传输矩阵的第2个对角元即可等运算优势.这些优势使得该方法不仅可以很好地进行理论分析, 还可以有效地简化分析过程和运算过程.

Abstract

Considering that the signal analysis is usually based on dual-way intensity detection, a novel method is demonstrated that uses Stokes vector method to analyze the degree of polarization degree in the optical fiber current sensor. In approximate conditions, the reduction transmission matrix is deduced and obtained of the full optical fiber current sensor based on Mueller matrix. It is found that the effect of the Stokes vector method is similar to the Jones vector method; by comparing the Jones vector method with the actual experimental results, it is easy to know that the Stokes vector has more operational advantages, such as only real numbers included in the Mueller matrix, easily being changed to sparse matrix and the final polarization degree being obtained by calculating the second diagonal element of the total transmission matrix. This method can be used in the theoretical analysis of the degree of polarization, and simplify the analysis process and operation process effectively.
