  • Abstract
    A high-resolution quasi-distributed strain sensor employing subcarrier interferometry and time-division multiplexing is reported. The system tracks a null in the subcarrier frequency response of a fibre network containing reflective discontinuities. Time gating selects the sensing section. A resolution better than 20 μm over 5 m lengths of fibre has been obtained
