Non-local effects in Brillouin optical time-domain analysis sensors
(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, ...
Compensation of nonlocal effects induced by the extinction ratio of pump pulses in Brillouin optical time-domain analysis sensors
(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 ...
Pulse coding linearization for Brillouin optical time-domain analysis sensors
(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 ...
