摘　　要：线性双折射严重削弱了光纤电流互感器性能,线性双折射测量是线性双折射抑制的基础。构建了线性双折射测量系统,提出了双偏振片调制法,据此消除传感光纤与相邻光器件之间方位角的影响;仿真研究了线性双折射测量中存在的多解问题,提出基于全局寻优算法的解决方案;在此基础上,分别测试三种不同传感光纤环的线性双折射。仿真结果表明:所述方法与邦加球法的测量偏差≤5%,方法可行。The linear birefringence weakens the performance of the optical fiber current sensor. The linear birefringence measurement is known to be the basis work of the linear birefringence suppress. First, the measurement system is built, and the double polarizer modulation is proposed to eliminate the effect between the sensing fiber and the surrounding optical elements. Then, the multi-value problem is simulated during the linear birefringence measurement, and the solution of this problem is proposed based on the global optimization.Finally, three different sensing fibers are tested. According to the results, the error between the proposed method and the Poincare method is not greater than 5%. It indicates that the proposed method is effective.
