Full color images using multiple diffraction gratings and masking techniques

A method of full-color reproduction of continuous-tone color pictures, images, or scenes by the use of diffraction grating techniques comprising:

• creating individual separation masks which delineate areas or zones dedicated to the reproduction of each of the primary colors,
• exposing a single photosensitive plate with an interference pattern representative of a primary color through each of said individual separation masks to form multiple diffraction grating latent images on said photosensitive plate,
• developing said photosensitive plate to convert said multiple diffraction grating latent images into surface relief diffraction gratings, and
• selectively causing gratings or portions thereof on the plate to be masked in order to leave the gratings or portions thereof all or partially diffracting so as to further render said plate into a unique pattern of active and inactive diffraction gratings reproducing the original colors in the original scene, image, or picture.

A method of full-color reproduction of continuous-tone color pictures, images, or scenes by the use of diffraction grating techniques comprising:

• generating a photosensitive plate means comprising multiple diffraction grating latent images thereon, said latent images delineating interference pattern areas or zones dedicated to the reproduction of each of the primary colors,
• developing said photosensitive plate means to convert said multiple diffraction grating latent images into surface relief diffraction gratings,
• replicating said photosensitive plate means where the replicas exhibit the same diffraction effects of said plate means, and
• selectively causing gratings or portions thereof on the plate means or a replica to be masked in order to leave the gratings or portions thereof all or partially diffracting so as to further render said plate means or said replica into a unique pattern of active and inactive diffraction gratings reproducing the original colors in the original scene, image, or picture.
