Real-time compressive sensing and recurrence sampling in comb spectroscopy
Abstract
We present a free-form dual-comb spectrometer that can be programmed to acquire signal that is most relevant to the application. By breaking the traditional dual-comb sensing strategy we can program real-time compressive sensing for reduction in measurement time, real-time apodization to tailor SNR and spectral resolution, and also recurrence sampling for fast imaging.
