Abstract

In this work we analyze a feasibility to use non-resonant polarization mode coupling in birefringent fiber for simultaneous strain and temperature quasi-distributed measuring. The method employs white light and a two-mode fiber containing in-fiber sensing interferometers. This technique allows us to interrogate local sensors and demultiplex output signals using a compact grating spectrometer. First experimental results are presented.
