Abstract

A new reflectometry, phase-modulating optical coherence domain reflectometry by synthesis of the coherence function (p-OCDR), is proposed in this paper. The optical coherence function synthesized by direct frequency modulation of a laser diode is scanned by phase modulation of a reference lightwave in an interferometer. This method has no mechanical moving part, and is easy to adjust a spatial resolution and a measuring range in optical circuits under test. Consideration of the influence of unideal factors to the performance of p-OCDR tells us that p- OCDR can realize a higher performance more easily than usual OCDR. Additionally p-OCDR can compensate a nonlinearity in the direct frequency modulation by the phase modulation. Finally basic experiments of p-OCDR are successfully carried out.
