Variation of Backscattered Brillouin Power an Effective Tool for Sensing Temperature

Abstract

Optical fiber which can be used for distributed sensing are employed to study backscattered power. The concept of Brillouin backscattering is employed in the proposed method. The focus is on the relation between the backscattered power and temperature changes in the fiber due to changes in fiber surroundings. The Brillouin backscattered light signal power can be used to obtain information about the temperature distribution along the fiber. Detailed simulation is done to validate the proposed method by designing system in the OptiSystem software.
