Compressive dual-comb spectroscopy

Compressive dual-comb spectroscopy

Abstract Broadband, high resolution, and rapid measurements of dual-comb spectroscopy (DCS) generate a large amount of data stream. We numerically demonstrate significant data compression of DCS spectra by using a compressive sensing technique. Our numerical simulation shows a compression rate of mo...
