Measurement of the distributed strain and temperature by modeling the Brillouin Spectrum

Actually, Structural health monitoring (SHM) presents an important field of researches, since we can monitor many civil structures using optical fiber sensors which give us the opportunity to explore the effect of shifting many parameters to detect and measure the influence of both temperature and strain in sensing fiber, we choose to work on Brillouin-scattering-based distributed sensor. In this paper, we make out the influence of shift temperature and strain in Brillouin scattering. The study proves the importance of Brillouin coefficients by fixing all of them. The Brillouin Spectrum will be modulating with Matlab codes.
