Temporal and Strain Dependence of Scattering Coefficients for Fiber Optic Sensing

This paper presents a detailed synthesis of modeling and simulations results of a distributed Brillouin sensor using a newly developed algorithm. The behaviors of the backscattered Brillouin and Rayleigh signals in the optical fibers are studied. Various magnitudes of temporal and strain in the presence of coherent Rayleigh noise are performed and compared with the published experimental results. A model establishing the temporal and strain dependence on scattering coefficients have been developed and discussed in this paper. All developed simulation models illustrate outstanding precision vis-a-vis published measurement results. The work carried out in this paper cemented approach for a more complex distributed Brillouin scattering modeling.
