Direct monitoring of fiber extension by correlation-based coherent optical time-domain reflectometry

By J.P.W. Hayward, S.J. Russell, J.P. Dakin and OFS-17


We propose a novel method of strain sensing where the displacement is measured by correlation of the coherent Rayleigh backscatter trace from a reference section of fiber. The potential performance is considered analytically and the theoretical results compared with the results of numerical simulations
