The robustness of a recently proposed Brillouin optical time-domain analysis sensor based
on dual-tone probe wave with fixed frequency separation is deeply studied. It is discovered …

The tolerance of the non-local effect in the BOTDA method using a dual-tone probe wave
with fixed frequency separation is theoretically and experimentally investigated in this paper …

The robustness of the BOTDA method based on dual-tone probe wave with fixed frequency
separation is studied. It is verified that when the sensing fiber consists of two fiber segments …

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 …

We present a novel technique for Brillouin optical time domain analysis (BOTDA) sensors
that simultaneously compensates non-local effects and reduces Brillouin noise. The …

In order to optimize the coherent Brillouin optical time domain analysis (BOTDA) sensor for
more effective chromatic dispersion (CD) suppression, single-sideband intensity-modulated …

The employment of coherent detection in a Brillouin optical time domain analysis (BOTDA)
fiber sensor brings benefits, including signal-to-noise ratio enhancement, non-local effect …

Conventional Brillouin optical time-domain analyzer (BOTDA) with a frequency-modulated
probe (FMP) could avoid non-local effects, while still suffering from the acoustic crosstalk …

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 …

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 …
