Pulsed stimulated Brillouin microscopy. [PDF]
Opt Express, 2023 Stimulated Brillouin scattering is an emerging technique for probing the mechanical properties of biological samples. However, the nonlinear process requires high optical intensities to generate sufficient signal-to-noise ratio (SNR). Here, we show that the SNR of stimulated Brillouin scattering can exceed that of spontaneous Brillouin scattering with ...

Heterodyne Brillouin microscopy for biomechanical imaging. [PDF]
Biomed Opt Express, 2021 Microscopic variations in material stiffness play a vital role in cellular scale biomechanics, but are difficult to measure in a natural 3D environment. Brillouin microscopy is a promising technology for such applications, providing non-contact label-free measurement of longitudinal modulus at microscopic resolution.

Brillouin microscopy: assessing ocular tissue biomechanics. [PDF]
Curr Opin Ophthalmol, 2018 Assessment of corneal biomechanics has been an unmet clinical need in ophthalmology for many years. Many researchers and clinicians have identified corneal biomechanics as source of variability in refractive procedures and one of the main factors in keratoconus. However, it has been difficult to accurately characterize corneal biomechanics in patients.

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 ...
