Abstract

A Faraday Rotating Brillouin Sensor System (FRoBS) is described and experimentally verified to reduce abrubt temperature/strain change distortions of the Brillouin Spectrum.This single-ended Brillouin System is created by modifying a typical Brillouin Optical Time-Domain Analysis system and adding a Faraday Rotating Mirror (FRM) and a Polarization Beam Splitter (PBS).Both lasers are combined with a PBS and are launched into the sensing fibre together.The remote end of the sensing fibre has a FRM attached that enables Brillouin measurement of the outgoing waves as well as the incoming waves, resulting in a mirrored time-domain waveform. Using weighted averages of the mirrored waveform results in a reduction in the aforementioned distortion.
