摘要
对扭转高圆双折射光纤中光的偏振态变化作了分析,提出用移动侧向变压力法测量高圆双折射光纤中的圆双折射,并在实验上用这种方法对扭转光纤首次作了测量。得到的测量结果与计算值(在已知光纤扭转率下)相对误差在2.4%之内.这一方法为高圆双折射光纤的无损检测提供了另一途径。
Based on the analysis of polarization variation in a highly circularlybirefringent(HCB) fibers, we proposed a method of moving lateral force to measure thecircular birefringence in the fibers. Using this method the twisted fiber was measuredexperimentally. The relative error between the results obtained from experiment andCalculation(under the condition of a known twist rate) is within 2. 4%. This methodprovids an alternative approach for the measuring of the HCB fiber non-destructively.
