Simple distributed Brillouin scattering modeling for temperature and strain sensing

摘要

This paper presents the synthesis of distributed Brillouin scattering modeling in optical fibers using a newly developed algorithm. The simulations of a distributed fiber optic sensor are carried out with the aim for temperature and strain sensing. The behaviors of Brillouin scattering in optical fibers are studied through the backscatter signals under various operating parameters along the optical fibers using the developed MATLAB codes. The analysis of backscatter signals characteristics when affected by temperature and strain are presented. All simulated models illustrate exceptional accuracy vis-à-vis published measurement results. The work carried out in this paper paved way for a more complex distributed Brillouin scattering modeling.
