A study is presented giving the response of three types of fiber-optic interferometers by which a standing wave through an object is investigated. The three types are a Sagnac, Mach-Zehnder and Michelson-Morley interferometer. The response of the Mach-Zehnder interferometer is similar to the Sagnac interferometer. However, the Sagnac interferometer is much harder to study because of the fact that one input port and output port coincide. Further, the Mach-Zehnder interferometer has the advantage that the output ports are symmetric, reducing the systematic effects. Examples of standing wave light absorption in several simple objects are given. Attention is drawn to the influence of standing waves in fiber-optic interferometers with weak-absorbing layers incorporated. A method is described for how these can be theoretically analyzed and experimentally measured. Further experiments are needed for a thorough comparison between theory and experiment.
本文介绍了一项关于三种类型光纤干涉仪响应的研究，通过这三种干涉仪研究了穿过物体的驻波。这三种类型分别是萨尼亚克（Sagnac）干涉仪、马赫-曾德尔（Mach-Zehnder）干涉仪和迈克尔逊-莫雷（Michelson-Morley）干涉仪。马赫-曾德尔干涉仪的响应与萨尼亚克干涉仪相似。然而，萨尼亚克干涉仪由于一个输入端口和输出端口重合这一事实，其研究难度要大得多。此外，马赫-曾德尔干涉仪具有输出端口对称的优点，可减少系统效应。文中给出了几种简单物体中驻波光吸收的示例。文中还提到了包含弱吸收层的光纤干涉仪中驻波的影响。描述了一种对这些情况进行理论分析和实验测量的方法。为了在理论和实验之间进行全面比较，还需要进一步的实验。
