摘要

Abstract: We present the implementation of a coherence receiver that is able, in parallel, to demultiplex and measure the phase between up to seven interference signals generated in a `white light' polarimetric quasi-distributed sensing system. It is based on a Michelson interferometer, one mirror of which has seven reflecting facets with differing thicknesses in its aperture. It was further used to measure the phase variation between two polarization couplers, versus three point bending loading for optical fibres either surface bonded or embedded in GRP composite, In both cases, the sensitivity to the composite elongation is found to be in close agreement with the sensitivity of the fibre itself.!7
