Brillouin optical time-domain analysis sensor assisted by Brillouin distributed amplification of pump pulses
(Optical Society of America, 2015)
Artículo / Artikulua,
We demonstrate the extension of the measurement range of
Brillouin optical time-domain analysis (BOTDA) sensors using a distributed
Brillouin amplifier (DBA). The technique is based on injecting a DBA
pump wave in the ...
Polarization diversity scheme for BOTDA sensors based on a double orthogonal pump interaction
(IEEE, 2015)
Artículo / Artikulua,
We introduce a Brillouin optical time domain analysis (BOTDA) sensor deploying a novel polarization diversity technique based on the use of two orthogonal pump pulses which simultaneously interact with a phase modulated ...
Overcoming non-local effects and Brillouin threshold limitations in Brillouin optical time domain sensors
(IEEE, 2015)
Artículo / Artikulua,
We demonstrate, for the first time to our knowledge, a Brillouin optical time domain analysis
(BOTDA) sensor that is able to operate with a probe power larger than the Brillouin threshold of the
deployed sensing fiber ...
