Faraday rotator mirror elements have been used in a number of applications as compensators for induced birefringence in retracing paths. In interferometric systems, such as the fiber-optic Michelson interferometer, this approach proved to be useful in providing maximum fringe visibility and insensitivity to the polarization state of light injected into the interferometer. However, it is found that, when the characteristics of the fiber coupler depend on the polarization state of the input beam, the efficiency of the Faraday mirror elements is limited. Theoretical analysis and experimental results in support of this statement are presented.
法拉第旋转镜元件已在许多应用中用作补偿回扫路径中感应双折射的元件。在干涉测量系统中，如光纤迈克尔逊干涉仪，这种方法被证明有助于提供最大条纹可见度，并且对注入干涉仪的光的偏振态不敏感。然而，人们发现，当光纤耦合器的特性取决于输入光束的偏振态时，法拉第镜元件的效率会受到限制。本文给出了支持这一说法的理论分析和实验结果。
