An approach to eliminating the effect of polarization pulling in Golay-coded Brillouin optical time domain analysis (BOTDA) fiber sensor by employing polarization division multiplexing (PDM) pulse coding is presented. Three different schemes, including polarization switching, polarization scrambling, and PDM pulse coding are implemented and compared. Experimental results indicate that sensing stability is enhanced by ~2.5 times using the proposed scheme.
