On-the-fly adaptive SNR protocol to accelerate Brillouin microscopy

Optics Express
This article presents an innovative method for accelerating Brillouin microscopy imaging. The proposed technique, called One-pass, dynamically adjusts the signal-to-noise ratio (SNR) during data acquisition. It identifies essential spectra in real-time and adapts the laser exposure time accordingly.

Large evanescently-induced Brillouin scattering at the surrounding of a nanofibre

Nature Communications, 2022
The authors observe efficient Brillouin scattering generated by an evanescent field nearby a single pass sub-wavelength waveguide. This work creates an important bridge between Brillouin scattering in waveguides, Brillouin spectroscopy and microscopy.

Improving localization precision of Brillouin measurements using spectral autocorrelation analysis [PDF]

Journal of Innovative Optical Health Sciences, 2017
Brillouin spectroscopy is a powerful tool for measuring the mechanical properties of materials without contact. The sensitivity to mechanical changes that a Brillouin spectrometer can detect is determined by the precision to which a spectral peak can be ...
