  • Abstract
    A novel technique for evaluating strain in multiple long-length sections of optical fibre is described. Sections defined by reflective markers are interrogated with subcarrier interferometry. Pathlength changes are monitored using cross-correlation. A resolution of 35 μm has been obtained over 5 m sensing sections, together with inter-section crosstalk levels below -45 dB
