Hyperspectral imaging provides spatially resolved spectral information. Utilising dual frequency combs as active illumination sources, hyperspectral imaging with ultra-high spectral resolution can be implemented in a scan-free manner when a detector array is used for heterodyne detection. However, relying on low-noise detector arrays, this approach is currently limited to the near-infrared regime. Here, we show that dual-comb hyperspectral imaging can be performed with an uncooled near-to-mid… Expand

Direct hyperspectral dual-comb imaging
The first hyperspectral dual-comb imaging system in which interferograms are directly detected by a video camera is presented, to the authors' knowledge, and is capable of characterizing a scene with super-fine resolution in a narrow optical span within 1 s. Expand
Photo-acoustic dual-frequency comb spectroscopy
The authors show that the resolution and speed limitations in broadband photo-acousticSpectroscopy can be overcome by combining dual-comb spectroscopy with photo-ACoustic detection, which enables broadband detection and allows for rapid and sensitive multi-species molecular analysis across all wavelengths of light.
