Distributed Acoustic Impedance Measurement Based On Forward Stimulated Brillouin Scattering

A technique to measure the local spectrum of forward stimulated Brillouin scattering (FSBS) along a standard optical fiber is proposed. The local acoustic impedance of surrounding material is retrieved from the measured FSBS resonance linewidth.
