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 ...
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 ...
