Paper Abstract

Distributed optical fiber sensors based on Brillouin scattering by measurement on time domain, due to its capability for strain and temperature measurement continuously for long range, are currently interesting. These sensors are based on spectral characteristics change of back scattered light at different places along the fiber. For this method Spatial resolution is limited by pulse length. We want to improve spatial resolution at time domain sensors by using of sinusoidal frequency modulation of pulse probe and continuous pump light. In this article, this method is simulated.
