| Abstract: | 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. |
