    • Quasi-distributed vibration sensing based on weak reflectors and STFT demodulation 

      Leandro González, Daniel Upna; Zhu, Mengshi; López-Amo Sáinz, Manuel Upna; Muruyama, Hideaki (IEEE, 2020)   Artículo / Artikulua
      In this work, a new system is proposed for quasi-distributed vibration sensing based on the Doppler effect. The setup employs an optical frequency domain reflectometer (OFDR) and an array of weak reflectors. The short-time ...
    • Quasi-distributed vibration sensing using OFDR and weak reflectors 

      Zhu, Mengshi; Leandro González, Daniel Upna; López-Amo Sáinz, Manuel Upna; Murayama, Hideaki (Optical Society of America, 2019)   Artículo / Artikulua  OpenAccess
      The authors proposed a quasi-distributed vibration sensing technique using in-line weak reflectors and optical frequency domain reflectometry (OFDR). As a result, they achieved an 8 kHz measurable vibration frequency with ...
