Brillouin optical time-domain analysis sensor with amplification of pump pulses and tolerant to non-local effects
Mompó Roselló, Juan José
; Urricelqui Polvorinos, Javier ; Loayssa Lara, Alayn (SPIE, 2016)
Contribución a congreso / Biltzarrerako ekarpena 
We demonstrate a simple technique to provide conventional Brillouin optical time-domain analysis sensor with compensation for pump pulse attenuation and tolerance to non-local effects. The technique is based on operating ... -
Brillouin optical time-domain analysis sensor with pump pulse amplification
Mompó Roselló, Juan José; Urricelqui Polvorinos, Javier ; Loayssa Lara, Alayn (Optical Society of America, 2016)
Artículo / Artikulua
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 ... -
Latest research on long-range Brillouin distributed sensing
Loayssa Lara, Alayn; Urricelqui Polvorinos, Javier ; Iribas Pardo, Haritz ; Mariñelarena Ollacarizqueta, Jon ; Mompó Roselló, Juan José (SPIE, 2019)
Contribución a congreso / Biltzarrerako ekarpena
We review the latest developments in long-range Brillouin optical time-domain analysis sensors. The factors that impair the performance of these sensors, particularly in terms of their distance range, are discussed together ... -
Non-local effects in Brillouin optical time-domain analysis sensors
Iribas Pardo, Haritz; Urricelqui Polvorinos, Javier ; Mompó Roselló, Juan José ; Mariñelarena Ollacarizqueta, Jon ; Loayssa Lara, Alayn (MDPI, 2017)
Artículo / Artikulua
Brillouin optical time-domain analysis (BOTDA) sensors have great potential to provide distributed measurements of temperature and strain over large structures with high spatial resolution and measurement precision. However, ... -
Second-order non-local effects mitigation in BOTDA sensors by tracking the BFS profile
Mompó Roselló, Juan José; Iribas Pardo, Haritz ; Urricelqui Polvorinos, Javier ; Loayssa Lara, Alayn (SPIE, 2017)
Contribución a congreso / Biltzarrerako ekarpena
We demonstrate a technique to mitigate the residual second-order non-local effects in Brillouin optical time-domain analysis (BOTDA) sensors in which the Brillouin frequency shift (BFS) profile is not uniform along the ... -
Second-order nonlocal effects mitigation in Brillouin optical time-domain analysis sensors by tracking the Brillouin frequency shift profile of the fiber
Mompó Roselló, Juan José; Iribas Pardo, Haritz ; Urricelqui Polvorinos, Javier ; Loayssa Lara, Alayn (IEEE, 2017)
Artículo / Artikulua
We report on an additional limitation that has been found in Brillouin optical time-domain analysis (BOTDA) sensors due to the so-called second-order nonlocal effects (NLE). Second-order NLE appear in BOTDA setups that ...
