    • Dual-probe linearly-configured BOCDA system with enlarged modulation amplitude 

      Mariñelarena Ollacarizqueta, Jon Upna; Kim, Yong Hyun; Loayssa Lara, Alayn Upna; Song, Kwang Yong (Optical Society of America, 2018)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      We present and experimentally demonstrated a linearly-configured Brillouin optical correlation domain analysis (LC-BOCDA) system that allows large modulation amplitude (Δf) based on a dual probe wave and the control of ...
    • Enhancement of the dynamic range in slope-assisted coherent brillouin optical time-domain analysis sensors 

      Mariñelarena Ollacarizqueta, Jon Upna; Urricelqui Polvorinos, Javier Upna; Loayssa Lara, Alayn Upna (IEEE, 2017)   Artículo / Artikulua  OpenAccess
      We present two techniques that provide an extension of the dynamic range of coherent Brillouin optical time-domain analysis (BOTDA) sensors for dynamic measurements. This type of BOTDA sensors rely on self-heterodyne ...
