Abstract :
A novel type of FTIR spectroscopy based on two coherent frequency combs is demonstrated. All-electronic interferogram recording allows simultaneous amplitude and phase spectra, and fast spectrum acquisition in 100 μs (1 μs anticipated), enabling single-event analysis. Diffraction-limited propagation suggests use in remote sensing, classical microscopy and scattering-type near-field microscopy.
