Frequency-domain technique to measure the inertial response of forward stimulated Brillouin scattering for acoustic impedance sensing
2017
Proceedings of the 25th International Conference on Optical Fiber Sensors
A frequency-domain method is proposed to measure the inertial response of forward stimulated Brillouin scattering, so that the acoustic impedance of a liquid medium outside an uncoated 30 m standard single-mode fibre can be sensed. The proposed technique overcomes the linewidth distortion present in the time-domain approach due to Kerr effect and reduce time and complexity for data post-processing. Experimental results demonstrate that acoustic impedances of water and ethanol agree well with the expected values.
