Crystalline-like ordering of 8CB liquid crystals revealed by time-domain Brillouin scattering [PDF]

open access: yesThe Journal of Chemical Physics, 2020
We demonstrate that time-domain Brillouin scattering (TDBS), a technique based on an ultrafast pump-probe approach, is sensitive to phase transitions and apply it to the study of structural changes in 8CB liquid crystals at different temperatures across the isotropic, nematic, smectic, and crystalline phases.

Application of the joint algorithm of smooth pseudo Wigner-Ville distribution and four-parameter particle swarm optimization to BOTDR

open access: yesResults in Physics, 2021
Short-time Fourier transform is utilized for the data processing of traditional point-frequency Brillouin optical time-domain reflectometry (BOTDR). This method can improve the measurement speed, but theoretically there is a contradiction between spatial

Time-domain Brillouin scattering for the determination of laser-induced temperature gradients in liquids [PDF]

open access: yesReview of Scientific Instruments, 2017
We present an optical technique based on ultrafast photoacoustics to determine the local temperature distribution profile in liquid samples in contact with a laser heated optical transducer. This ultrafast pump-probe experiment uses time-domain Brillouin scattering (TDBS) to locally determine the light scattering frequency shift.

Characterization of the Noise Induced by Stimulated Brillouin Scattering in Distributed Sensing

open access: yesSensors, 2020
The excess noise due to stimulated Brillouin scattering (SBS) in gain and loss-based Brillouin optical time-domain analyzers (BOTDA) has been investigated theoretically and experimentally for the first time to the best of our knowledge.
