Paper Abstract

The feasibility of polychromatic object recognition by multichannel correlation is experimentally demonstrated. Objects whose shape changes with the wavelength of the illumination beam are used. Separate high-pass matched filters, each one recorded with a different wavelength, are successively employed to perform the recognition of a polychromatic signal without ambiguity. Results of numerical simulation are also presented.
