Distributed Acoustic Impedance Measurement Based On Forward Stimulated Brillouin Scattering
November 21, 2018
26th International Conference on Optical Fiber Sensors, OSA Technical Digest
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.
