We present a novel hyperspectral imaging system working in the visible and in the short-wave infrared (SWIR) spectral region based on a Fourier-transform (FT) approach. The technology presents high light throughput and spatial resolution, a software adjustable spectral resolution, and a wide versatility of use. It employs a common-path interferometer, generating two replicas of the image with controllable delay and remarkable accuracy and stability. The monochromatic camera (CMOS, CCD, or InGaAs bidimensional sensor) does not require any relative movement with respect to the sample. The absence of gratings and slits guarantees an exceptional throughput that ensures high-quality data even at the lowest light dose, making this technology particularly suitable in fluorescence studies, or where low-illuminance conditions are recommended in order not to damage the samples. We will show several examples of the use in remote sensing and microscopy.
