Sources of noise in Brillouin optical time-domain analyzers
(SPIE, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
This paper presents a thorough study of the different sources of noise affecting Brillouin optical time-domain analyzers (BOTDA), providing a deep insight into the understanding of the fundamental limitations of this kind ...
Mitigation of modulation instability in Brillouin distributed fiber sensors by using orthogonal polarization pulses
(SPIE, 2015)
Contribución a congreso / Biltzarrerako ekarpena,
A technique based on the use of orthogonally-polarized pulses is proposed to mitigate the detrimental impact of modulation
instability on Brillouin distributed fiber sensors. While the theoretical underpinnings of the ...
Phase-shift based BOTDA measurements tolerant to non-local effects
(SPIE, 2013)
Contribución a congreso / Biltzarrerako ekarpena,
We demonstrate a BOTDA sensor based on the use of the Brillouin phase shift that performs measurements tolerant to non local effects. This technique raises opportunities to increase the distance covered by these sensors ...
Brillouin optical time-domain analysis sensor with amplification of pump pulses and tolerant to non-local effects
(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 ...
Investigation on the working point of slope-assisted dynamic Brillouin distributed fiber sensing
(SPIE, 2019)
info:eu-repo/semantics/conferenceObject,
In this paper, an investigation on the working point of slope-assisted dynamic distributed Brillouin sensing is presented. A comparison has been carried out between the sensing performances achieved at the inflection point ...
