Frequency-domain analysis of stimulated Brillouin scattering in single-mode optical fibers

A reconstruction algorithm employing an accurate modelling of the stimulated Brillouin scattering (SBS) interaction in a single-mode optical fibre, is experimentally demonstrated. Distributed strain/temperature measurements are carried out by using a Brillouin optical frequency-domain analysis configuration. Reconstructions are carried out by fully taking into account the influence of the modulation of the acoustic wave involved in the SBS interaction.
