Hyperspectral Unmixing for Raman Spectroscopy Using Autoencoders



The author showcases a novel photon-counting approach in near-ultraviolet dual-comb spectroscopy, enabling high-resolution frequency calibration and signal-to-noise ratio at the quantum limit.


We demonstrate a photon-counting approach that extends the unique advantages of spectroscopy&nbsp;with interfering frequency combs into regions where nonlinear frequency conversion tends to be very inefficient, providing a step towards precision broadband spectroscopy at short wavelengths and extreme-ultraviolet dual-comb spectroscopy.
