光纤白光干涉仪等臂长技术研究

Study of methods of zero optical path difference in fiber interferometer

介绍了几种光纤干涉仪等臂长技术,比较了各自的优缺点和适用范围,对光纤干涉仪的平衡有较大的参考价值。

For optical fiber white interferometer,interference occurs only if optical path difference is less than coherence length of light source.Several methods,which can balance the interferometer are introduced.Their advantage and shortcoming are compared.This is valuable for application of optical fiber interferometer.
