We introduce a compact hyperspectral camera based on the time-domain Fourier-transform approach, equipped with an ultrastable birefringent interferometer. The time-domain approach enables hyperspectral imaging with shorter acquisition times and higher spectral accuracy compared to standard dispersive optics. We provide experimental proofs of the camera capability by performing remote-sensing measurements in the visible and near-infrared range. Recently we extended the spectral range to the thermal infrared, where vibrational transitions associated with chemical bonds have their absorption. Due to its compactness, lightweight and extreme stability even in harsh environments, the camera is a unique enabling technology for remote unambiguous chemical identification.
