A Supercontinuum source is used with a static Michelson interferometer to perform high-resolution optical coherence-domain reflectometry (OCDR) at 1.551μm. Quadrature spectral detection enables compensation for both the undesirable spectral shape of the source and for the dispersion in the system. A resolution of less than 5μm in fibre (full width at half maximum) at 1.55μm is obtained.
