Abstract

Employing stimulated Brillouin scattering (SBS), we present a novel method for the quasi-simultaneous distributed measurement of dynamic strain along an entire Brillouin-inhomogeneous optical fiber. Following classical mapping of the temporally slowly varying Brillouin gain spectrum (BGS) along the fiber, we use a specially synthesized and adaptable probe wave to always work on the slope of the local BGS, allowing a single pump pulse to sample fast strain variations along the entire fiber. Strain vibrations of tens of Hertz and up to 2KHz are demonstrated, simultaneously (i.e., using the same pump pulse) measured on two different segments of the fiber, having different static Brillouin shifts.
