提出了一种利用光纤偏振旋转器（FPR）减小反射式光纤电流传感器（FOCS）中弯曲引起的线性双折射（LB）的新技术。建立了精确的琼斯矩阵模型。基于该模型，评估了这种LB对FOCS性能的影响。对所提出的FPR方案与传统方案的测量误差进行了比较。仿真结果表明，所提出的方案有很大的改善，这样的LB减少了一个数量级。
We propose a new technique to reduce the bending- induced linear birefringence (LB) by fiber polarization rotator (FPR) in the reflective fiber-optical current sensor (FOCS). An accurate Jones matrix model was established. Such LB influence on FOCS performance is evaluated based on this model. A comparison was made between the proposed FPR scheme and the conventional scheme on measurement errors. Simulation shows that the proposed scheme has a large improvement on such LB reduction by an order of magnitude.
