Compensation of nonlocal effects induced by the extinction ratio of pump pulses in Brillouin optical time-domain analysis sensors
Mariñelarena Ollacarizqueta, Jon
; Iribas Pardo, Haritz ; Urricelqui Polvorinos, Javier ; Loayssa Lara, Alayn (Optical Society of America, 2019)
Artículo / Artikulua 
We demonstrate a technique to compensate the nonlocal effects that appear in Brillouin optical time-domain analysis sensors when pump pulses with limited extinction ratio are deployed. These recently discovered nonlocal ... -
Cost-effective Brillouin optical time-domain analysis sensor using a single optical source and passive optical filtering
Iribas Pardo, Haritz ; Urricelqui Polvorinos, Javier ; Mariñelarena Ollacarizqueta, Jon ; Sagüés García, Mikel ; Loayssa Lara, Alayn (Hindawi Publishing Corporation, 2016)
Artículo / Artikulua
We present a simplified configuration for distributed Brillouin optical time-domain analysis sensors that aims to reduce the cost of the sensor by reducing the number of components required for the generation of the two ... -
Effects of pump pulse extinction ratio in Brillouin optical time-domain analysis sensors
Iribas Pardo, Haritz ; Mariñelarena Ollacarizqueta, Jon ; Feng, Cheng; Urricelqui Polvorinos, Javier ; Schneider, Thomas; Loayssa Lara, Alayn (Optical Society of America, 2017)
Artículo / Artikulua
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 ... -
Enhancement of the dynamic range in slope-assisted coherent brillouin optical time-domain analysis sensors
Mariñelarena Ollacarizqueta, Jon ; Urricelqui Polvorinos, Javier ; Loayssa Lara, Alayn (IEEE, 2017)
Artículo / Artikulua
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 ... -
Gain dependence of the phase-shift spectra measured in coherent Brillouin optical time-domain analysis sensors
Mariñelarena Ollacarizqueta, Jon ; Urricelqui Polvorinos, Javier ; Loayssa Lara, Alayn (IEEE, 2016)
Artículo / Artikulua
We report on the effects of large pump pulse powers on Brillouin optical time-domain analysis (BOTDA) sensors based on phase-modulated probe wave and coherent self-heterodyne detection. These sensors are particularly ... -
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, ... -
Pulse coding linearization for Brillouin optical time-domain analysis sensors
Mariñelarena Ollacarizqueta, Jon ; Iribas Pardo, Haritz ; Loayssa Lara, Alayn (Optical Society of America, 2018)
Artículo / Artikulua
We introduce a simple method to extend the performance of pulse coding techniques in their application to Brillouin optical time-domain analysis sensors (BOTDA). It is based on applying a simple logarithmic processing on ...
