摘要
利用温度对相位调制的全光纤Mach-Zehnder结构型温度传感器,采用CCD摄像头与小型电视连接的办法来观察干涉条纹的移动,并给出温度变化与干涉条纹移动数的关系,以及敏感长度与灵敏度的关系,进一步了解干涉仪作为温度传感器的参数特性及其作为一台测量仪器的定标。
In this thesis, we have an acquaintance with the full fiber optic temperature transducer Mach- Zehnder based on phase modulation by temperature, and observe the moving of interferential stripes through CCD camera connected with miniature TV set, and give out the relations between variation of temperature and moving of these stripes, and between sensitive length and sensitivity. Furthermore, we also have an knowledge of parameter characteristics of the interferometer as temperature transducer and calibration of it as a metrical apparatus.
