Abstract
Distributed discrimination of strain and temperature is demonstrated by localizing both the stimulated Brillouin scattering (SBS) and the dynamic acoustic grating generated in the SBS process in a polarization-maintaining fiber with a correlation-domain continuous-wave technique. A 12- ???? strain resolution and 0.3??C temperature resolution together with a 10-cm spatial resolution are experimentally validated.
