Schematic diagrams of an RGB camera (a) and a typical hyperspectral imager (b). In an RGB image, each pixel is combined with three discrete color values, which is integrated from wide R, G, B spectra. In a hyperspectral image, each pixel is a continuous spectral curve that is filtered from a series of narrow spectral bands. FL focusing lens group, FO front objective, CL collimating lens group. The image data are from the KAUST-HS open-source dataset26.
