Pulsed heterodyne Brillouin detection enables high-resolution epi-detected biomechanical microscopy and endoscopy
Zixuan Du, Shuai Yao, Yun Qi +12
Brillouin microscopy enables non-contact, three-dimensional mapping of viscoelasticity in living systems, yet two long-standing limitations have constrained its biological reach: t…

Impact of refractive index heterogeneity on stimulated Brillouin scattering microscopy: a quantitative analysis
Meng Xu, Zixuan Du, Yun Qi +4
Stimulated Brillouin scattering (SBS) microscopy enables label-free biomechanical imaging, with Brillouin gain serving as a critical contrast parameter for quantitative analysis. H…
