dute. Lan honetan, BOTDA konfigurazio ...
Detrimental effects in Brillouin distributed sensors caused by EDFA transient
(Optical Society of AmericaIEEE, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
We investigate the deleterious effect and the error in Brillouin optical time-domain analyzers induced by the combination of a low extinction ratio pulse generation with the transient behavior of erbium-doped fiber amplifiers.
Second-order nonlocal effects mitigation in Brillouin optical time-domain analysis sensors by tracking the Brillouin frequency shift profile of the fiber
(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 ...
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 ...
Second-order non-local effects mitigation in BOTDA sensors by tracking the BFS profile
(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 ...
Cyclic coding for Brillouin optical time-domain analyzers using probe dithering
(Optical Society of America, 2017)
Artículo / Artikulua,
We study the performance limits of mono-color cyclic coding applied to Brillouin optical time-domain analysis (BOTDA) sensors that use probe wave dithering. BOTDA analyzers with dithering of the probe use a dual-probe-sideband ...
Latest research on long-range Brillouin distributed sensing
(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 ...
