• Dynamic BOTDA measurements using Brillouin phase-shift 

      Urricelqui Polvorinos, Javier Upna; Zornoza Indart, Ander; Sagüés García, Mikel Upna; Loayssa Lara, Alayn Upna (SPIE, 2012)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      We demonstrate a novel dynamic BOTDA sensor based, for the first time to our knowledge, on the use of the Brillouin phase-shift instead of the conventional Brillouin gain. This provides the advantage of measurements that ...
    • Phase-shift based BOTDA measurements tolerant to non-local effects 

      Urricelqui Polvorinos, Javier Upna; Sagüés García, Mikel Upna; Loayssa Lara, Alayn Upna (SPIE, 2013)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      We demonstrate a BOTDA sensor based on the use of the Brillouin phase shift that performs measurements tolerant to non local effects. This technique raises opportunities to increase the distance covered by these sensors ...
