Abstract

A distributed fiber sensor which can simultaneously measure the strain and vibration of fiber is proposed. Only the Brillouin scattering is used for the measurement with a heterodyne detection scheme. In the Brillouin scattering, the Brillouin frequency shift is utilized for the strain measurement and the state of polarization is utilized for the vibration measurements. Experimental results proved a distributed fiber strain and vibration sensor which can achieve 11.5 km sensing distance, 10 m spatial resolution, 26 Hz frequency measurement range, 0.8 Hz frequency resolution and 0.1 MHz uncertainty of Brillouin frequency measurement.
