文章在深入分析各种光纤物理特性的基础上，根据不同的应用环境对传感光纤做了选择，搭建了基于全光纤Mach-Zehnder干涉仪的布里渊散射谱测量系统，实现了对所选传感光纤在常温下布里渊频移的定性测量，并对普通通信单模光纤的布里渊频移的温度依赖性进行了定性测量。设计了基于布里渊散射的光时域反射计。

Optical fibers for sensing are first selected for different applications on the basis of in-depth analysis of their physical characteristics. Then a Brillouin scattering spectrum measurement system based on the all fiber Mach-Zehnder interferometer is built, the qualitative measurement of the Brillouin frequency shift of the chosen fibers in normal temperature and the temperature dependence of G.652 fibers respectively performed. Finally, a Brillouin scattering-based time domain reflectometer is designed.
