Abstract

A wide-range OFDR strain sensor based on UV-exposed-SMF and distance compensation method was demonstrated. A UV-exposed-SMF with Rayleigh backscattering (RBS) enhancement of 35.4 dB was successfully obtained to improve the signal-to-noise ratio. By combining distance compensation method, the strain, up to 9000 με, could be successfully demodulated under the spatial resolution of 1.5 mm.
