    • Detrimental effects in Brillouin distributed sensors caused by EDFA transient 

      Feng, Cheng; Iribas Pardo, Haritz Upna; Mariñelarena Ollacarizqueta, Jon Upna; Schneider, Thomas; Loayssa Lara, Alayn Upna (Optical Society of AmericaIEEE, 2017)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      We investigate the deleterious effect and the error in Brillouin optical time-domain analyzers induced by the combination of a low extinction ratio pulse generation with the transient behavior of erbium-doped fiber amplifiers.
    • Effects of pump pulse extinction ratio in Brillouin optical time-domain analysis sensors 

      Iribas Pardo, Haritz Upna; Mariñelarena Ollacarizqueta, Jon Upna; Feng, Cheng; Urricelqui Polvorinos, Javier Upna; Schneider, Thomas; Loayssa Lara, Alayn Upna (Optical Society of America, 2017)   Artículo / Artikulua  OpenAccess
      We report on two previously unknown non-local effects that have been found to impair Brillouin optical time-domain analysis (BOTDA) sensors that deploy limited extinction ratio (ER) pump pulses. The first one originates ...
