Adaptive Optics for Brillouin Micro-Spectroscopy

Brillouin spectroscopy is a powerful optical technique for non-contact viscoelastic characterizations enabling three-dimensional mapping of biological samples. Here we present an adaptive-optics configuration for Brillouin spectroscopy providing 2.5-fold enhancement in Brillouin signal strength and 1.4-fold improvement in axial resolution by correcting for sample induced aberrations.
