Abstract: We report a new method for reconstructing the signal shape of the external dynamic perturbations along the entire length of the fibre of an optical coherence reflectometer. The method proposed is based on differential phase-shift keying of a probe pulse and demodulation of scattered light by the phase diversity technique. Possibilities of the method are demonstrated experimentally.

Keywords: phase-sensitive reflectometer, optical coherence reflectometer, scattered radiation, differential phase modulation, phase diversity.
