High-speed Vibrational Microscopy and Deep-Learning Algorithms to Image Cells and Tissues

Coherent Raman scattering (CRS) microscopy is a powerful third-order nonlinear optical technique for label-free chemical identification of molecules based on their intrinsic vibrational spectrum. It can reach video-rate imaging speed and detect very dilute species. I will review the working principles and state of the art of this technique, presenting our recent results and perspectives. I will also show how artificial intelligence methods can be employed effectively to increase the signal-to-noise ratio and extract the relevant information from the large experimental hyperspectral datacubes.
