Optical fiber sensors based on stimulated Brillouin scattering in optical fibers have now clearly demonstrated their excellent capability for long-range distributed strain and temper- ature measurements. The fiber is used as sensing element and a valuefortemperatureand/orstraincanbeobtainedfromanypoint along the fiber. While the spatial resolution of classical configura- tions is practically limited to 1 meter by the phonon lifetime, novel approacheshavebeendemonstratedthesepastyearsthatcanover- come this limit. In this paper, this could be achieved by two phys- ical processes: prior activation of a steady acoustic wave through the classical Brillouin interaction between two Brillouin pumps, and interrogation by Bragg reflection on the acoustic wave using a distinct ultra-short pulse in a highly birefringent fiber. We could achieve a spatial resolution below one centimeter, while preserving the full accuracy on the determination of temperature and strain.
