    • Brillouin optical time-domain analysis sensor assisted by Brillouin distributed amplification of pump pulses 

      Urricelqui Polvorinos, Javier Upna; Sagüés García, Mikel Upna; Loayssa Lara, Alayn Upna (Optical Society of America, 2015)   Artículo / Artikulua  OpenAccess
      We demonstrate the extension of the measurement range of Brillouin optical time-domain analysis (BOTDA) sensors using a distributed Brillouin amplifier (DBA). The technique is based on injecting a DBA pump wave in the ...
    • Brillouin optical time-domain analysis sensor with pump pulse amplification 

      Mompó Roselló, Juan José Upna; Urricelqui Polvorinos, Javier Upna; Loayssa Lara, Alayn Upna (Optical Society of America, 2016)   Artículo / Artikulua  OpenAccess
      We demonstrate a simple technique to provide conventional Brillouin optical time-domain analysis sensors with mitigation for pump pulse attenuation. The technique is based on operating the sensor in loss configuration so ...
