Abstract :
A static Michelson interferometer coupled with optical spectral analysis has been used to perform optical coherence-domain reflectometry (OCDR). Compensation of both the coherence sidelobes caused by a non-Gaussian source spectrum and the coherence broadening caused by dispersion is shown. Reflections indistinguishable using an EDFA source and conventional scanning OCDR are clearly distinguished with this method.
