| Abstract(in English) | We propose a single-end-access distributed fiber-optic correlation-domain sensor based on stimulated Brillouin scattering (SBS) in a polarization-maintaining optical fiber (PMF). Both pump and probe waves are sinusoidally frequency-modulated and input into one end of the PMF with orthogonal polarization states. Assisted by a polarization beam splitter and a polarization-maintaining isolator installed at the other end of the PMF, SBS interaction between the reflected probe wave and the forward pump wave is exclusively localized within the PMF. Unlike the previously-reported reflector-based method, neither an optical filter nor a sophisticated beat-lock-in detection is necessary. Distributed sensing of temperature or strain is experimentally demonstrated with the measurement range and the spatial resolution of 200m/16cm, 56m/5cm, or 5.6m/5mm, respectively. |
