    Development of a Phase-OTDR interrogator based on coherent detection scheme
    (Bursa Uludağ Üniversitesi, 2018-12-14) Yüksel, Kıvılcım; Jason, Johan; Wuilpart, Marc
    We present in this work, the experimental demonstration of a phase-sensitive Optical TimeDomain Reflectometer (phase-OTDR) having coherent detection scheme. An analysis algorithm has also been developed to calculate amplitude and phase evolution of the experimental phase-OTDR traces. The efficiency of the analysis algorithm to determine the position of the applied vibration has been verified for a single and two simultaneous vibrations. The slow-time analysis results show a good agreement with the mathematical calculations discussed in the paper. This work could have a technological implication in many fields such as distributed vibration sensor for railway monitoring applications.
