Abstract

We demonstrate for the first time true distributed sensing of scale and location of transverse loading along an extended length of polarisation maintaining [PM] fibre with high spatial resolution using Optical Frequency Domain Reflectometry [OFDR]. Transverse loading of PM fibres induces local and differential changes in refractive index in slow and fast axis, depending on scale and direction of load relative to the axes. The change in refractive index is detected by monitoring the change in local periodicity of the statically distributed Rayleigh scatter for each PM fibre axis simultaneously using OFDR. © 2009 SPIE.
