Abstract

We review our work on a novel dual-comb technique to achieve a customized temporal expansion of the time-domain trace in a phase-sensitive reflectometer, that allows dynamic interrogation of strain/temperature in optical fibres with high spatial resolution (in the cm range) using only low-bandwidth photodetection (~MHz).
