| Abstract: | The applications and advantages of Mach-Zehnder interferometer in the two aspects of sensing and demodulation have been primarily introduced. On the sense field, strain and temperature both can arouse the phase change of Mach-Zehnder interferometer. A sensor system is used to measure strain and temperature which exploited Mach-Zehnder interferometer and fiber Bragg grating was proposed based on this, and its operating principle was analyzed. |
