Abstract
We experimentally demonstrate compressed time-domain coherent Raman spectroscopy with real-time random sampling. Specifically, we employ Fourier-transform coherent anti-Stokes Raman scattering as a platform for the spectroscopy and demonstrate reconstruction of Raman spectra from sparsely sampled time-domain interferograms using the iterative shrinkage-thresholding algorithm. We show that Raman spectra reconstructed at compression ratios down to 0.3 retain the quality of a fully sampled Raman spectrum. We also verify this performance with multiple molecules to demonstrate its versatility. Advantages of our method include data volume reduction, signal acquisition time reduction, and alleviated requirements for measurement instruments. © 2019 Optical Society of America.
