Abstract: In a real-time color comparator which performs color comparisons of sample objects to a reference color for the purpose of identification, sorting or matching two optical paths (15, 16) are positioned to collect the light from a reference object (12) and a sample object (11). The light outputs from the two paths are directed onto a spectral dispersive element in the form of a concave diffraction grating (20) that decomposes each light signal into its spectral constituents which are imaged on a dual photodetector array (30). The color signature from the reference and the color signature from the sample are compared.

Abstract: A color signature sensor for color recognition or discrimination utilizes a spectral analysis system and may be used in process control or on-line quality assurance. An object (11) to be observed is illuminated by a suitable light source (10), light collected from the object under examination is routed into a monochrometer (16). The output of the monochrometer is fed to an analog-to-digital converter (19) and analyzed by a microprocessor (18).
