THE NEW POSSIBILITIES THAT SPECTRAL IMAGING BRINGS TO MACHINE VISION

With spectral imaging, different materials can be recognized and seperated. Recognition is done by lighting the object and analyzing the lights behaviour on the objects sufrace. For recognition, a spectral camera and a lighting source is only needed for getting the spectrum of an object. Every material has their own known chemical structure. When an object is lighted, how light beams act on the objects surface depends straight on the materials structure. With spectral
