Hyperspectral imaging, like other spectral imaging, collects and
processes information from across the electromagnetic spectrum. The
goal of hyperspectral imaging is to obtain the spectrum for each pixel
in the image of a scene, with the purpose of finding objects,
identifying materials, or detecting processes. Hyperspectral sensors
look at objects using a vast portion of the electromagnetic spectrum.
Certain objects leave unique 'fingerprints' in the electromagnetic
spectrum.
