A phase-sensitive coherence reflectometer with amplitude-phase modulation of probing pulses

摘要

Results of investigation of a phase-sensitive fiber-optic coherence reflectometer with amplitude-phase modulation of probing pulses are presented. Using this method of modulation, it is possible to reconstruct the signal of external impact upon the reflectometer fiber by means of the phase diversity technique. The applicability of the proposed method is theoretically justified and experimentally verified.
