FIELD: technological processes.
SUBSTANCE: method consists in transferring the electronic version of the original to a multilayer sheet material consisting of a layer of plastic with two parallel metallized diffraction gratings, covered with a layer of metallized foil, by the action of pulses of laser radiation at given points on the surface of the material, the creation of channels in the metal layer of the foil, and the interaction of each laser pulse with the dashes of the diffraction gratings. Rays reflected from the diffraction gratings form pairs of bulk nanostructures with copies of fragments of diffraction gratings deposited on them directly in the optical channels of the foil in the layer of its plastic, create in these channels a latent image of a plurality of pairs of bulk nanostructures and visualize this image by glowing bulk nanostructures that passed through the channels in the metal layer of the foil and the light flux that has undergone dispersion.
EFFECT: ensuring the highest possible brightness of the image.
