Abstract

A reconstruction algorithm employing an accurate modeling of the stimulated Brillouin scattering (SBS) interaction in a single-mode optical fiber, is experimentally demonstrated. Distributed temperature measureme nts 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. The sensor shows good accuracy in determining any temperature disturbances as narrow as 40 centimeters placed along the fiber.
