Reduction of Acquisition Time in FTIR Spectroscopy via Spectral Super-Resolution by Deep Learning

-means clustering. Our spectral super-resolution approach offers an efficient solution to overcome the limitations of IR image acquisition time, enabling a reduction in an acquisition time of up to 87.5% while preserving similar spectral quality. These advancements pave the way for faster infrared spectral imaging acquisitions while preserving the molecular information contained in high-resolution spectra, which is an important step toward future clinical applications.
