Paper Abstract

We propose a method to shift whole the shape of synthesized optical coherence function along an optical path by phase modulation. We can synthesize periodical delta function type optical coherence peaks by frequency modulation of a light source to realize distributed measurement of back-scattering and/or reflections along an optical fiber by sweeping the coherence peak as measurement window. In this study, we propose and demonstrate a method to synthesize and sweep the 0th coherence peak by phase modulation with the same waveform as that for the laser frequency modulation. Basic experiments of optical reflectometry are successfully demonstrated with the proposed method.
