Wang Tingjun1, Cheng Xiaowei2, Li Xudong2. Design of fiber sensing system based on Brillouin scattering characteristics[J]. 2008,(1):48-50. DOI: 10.13756/j.gtxyj.2008.01.022.
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.
