【摘要】 分析了单模光纤由弯曲引起的双折射，推导了弯曲双折射的计算公式，并建立了测量弯曲双折射的实验方法和装置。实验结果显示它与理论计算结果有好的吻合。该工作对消除光纤法拉第电流传感器的双折射影响具有很重要的意义。更多还原

【Abstract】 The birefringence in single-mode optical fibers caused by bending is presented. Calculation of bending-induced birefringence is theoretically derived. The measuring approach is experimentally set up. The theoretical and experimental results show excellent agreement更多还原
