Abstract

Raman microscopy is a valuable approach to label-free chemical imaging. Recent advances have enabled the development of rapid methods for hyperspectral microscopy using impulsive stimulated Raman scattering (ISRS) that focus on low-frequency Raman modes of materials. The persistent challenge with Raman spectroscopic methods is low signal due to the relatively weak Raman scattering. ISRS microscopy allows for high quality hyperspectral imaging of low and fingerprint Raman vibrational frequencies but is normally subject to poor performance in the presence of optical scattering. We will present methods that solve this issue and allow for high-quality imaging when strong optical scattering is present.
