Dual-comb spectrometer is a novel Fourier transform spectrometer based on the multi-heterodyne detection of two pulse trains with slight different repetition rates. Dual-comb spectroscopy can achieve broad-bandwidth, high-resolution and fast spectral acquisition simultaneously. In this report, the principle of dual-comb technique and recent developments and applications will be presented.
