Paper Abstract

We present a novel technique for dynamic strain measurements in optical fibers, based on the stimulated Brillouin scattering interaction between two counter-propagating optical pulses. The technique permits to address dynamically and randomly the position at which vibration is measured. Moreover, in the proposed method the sampling rate is only limited by the time-of-flight of the pulses along the sensing fiber. Preliminary experimental results, carried out with a perturbation frequency up to 98 Hz, demonstrate the validity of the proposed technique.
