Abstract

A novel OTDR technique to accurately monitor the optical path length to multiple reflective markers is described. The method can monitor changes in optical path length of 40 ppm in a 1 sec measurement time and is suitable for multiplexed optical-fibre strain sensing over gauge lengths of several metres.
