发明名称 PROCEDE UNIVERSEL D'IDENTIFICATION ET D'AUTHENTIFICATION D'OBJETS, DE VEGETAUX OU D'ETRES VIVANTS
摘要 <p>Reading of unique non - reproducible volume identifier (100) of type including mix of at least two distinguishable materials (110,120). Recognize internal heterogeneous structure in two dimensions of the identifier then show evidence to prove its third dimension. Show the volume disposition of material arrangement contained in identifier by analysis of shadows (121) generated by material as function of incidence angle of light with respect to the identifier. The identifier contains bubbles (120). Read and show the volume disposition of the bubbles contained in the identifier (100) by successive submission, without delay of the identifier, to a diffused light produced by a projection (700) along two dimensions of the bubble contours which allows reading and coding. Then submit to illumination which generates a reflection at the interface (800) which separates the heterogeneity of the transparent product (110) so as to prove its volume aspect. Show the volume disposition (800) of the identifier (100) by analysis of the shapes reflected by the bubbles (120) contained in the identifier (100) as a function of the illumination. The method uses a bank of lamps passing from one state to another. Two set of lamps are illuminated to create diffuse lighting or a single set is illuminated to create a beam. The identifier is a transparent material (110) whose bubbles are auto-generated by a thermal process during hardening of the transparent material.</p>
