This article presents a novel distributed forward stimulated Brillouin scattering measurement scheme on polarization maintaining fiber (PM fiber) with a spatial resolution of 0.8 m named polarization separation assisted opto-mechanical time-domain analysis (PS-OMTDA). The activation pulse is injected into the fast axis and the probe pulse and probe wave is injected into the slow one, therefore, the acoustic wave is excited upon the fast axis but affected the probe wave on the slow axis. The backward Brillouin scattering of an activation pulse is effectively suppressed by isolating the acoustic activation and probing process. A spatial resolution of 80 cm is experimentally demonstrated over a PM fiber with a length of 34 m.
