A Novel Approach for Simple Distributed Brillouin Scattering Modeling for

This paper presents simulations of a distributed fiber optic sensor for temperature and strain sensing. The behaviors of Brillouin and Rayleigh scattering in optical fibres are studied through the backscatter signals. The analysis includes the characteristics of backscatter signals when affected by temperature and strain. A new algorithm is developed to efficiently determine the backscattered Brillouin signal for a given input pump power. All the developed simulation models exhibit exceptional analysis accuracy as verified through comparison with the published measurement results
