The use of a fiber-optic Mach-Zehnder interferometer to measure differences in temperature or pressure between two single-mode fiber arms is described. Temperature or pressure changes are observed as a motion of an optical interference fringe pattern. Values are calculated for the pressure and temperature dependence of the fringe motion. Pressure and temperature measurements are made with the interferometer, and the experimental values for sensitivity are in good agreement with those calculated.
本文描述了使用光纤马赫-曾德尔干涉仪测量两个单模光纤臂之间的温度或压力差的方法。温度或压力变化表现为光学干涉条纹图案的移动。计算了条纹移动对压力和温度的依赖值。使用该干涉仪进行压力和温度测量，实验得到的灵敏度值与计算值吻合良好。
