Abstract

L'invention concerne un élément d'identification optique (8) qui comprend un substrat optique (10) dans lequel est disposé au moins un réseau de diffraction (12). Ce réseau (12) présente un ou plusieurs pas regroupés ? qui représentent un code numérique binaire N d'identification unique qui est détecté lorsqu'il est éclairé par une lumière incidente (24). Cette lumière incidente (24) peut être dirigée de manière transversale sur le côté ou sur une extrémité du substrat (10) au moyen d'une source à bande étroite (simple longueur d'onde) ou à plusieurs longueurs d'onde, auquel cas le code est représenté respectivement par une distribution spatiale de lumière ou un spectre de longueur d'onde. L'élément (8) peut fournir un grand nombre de codes uniques, par exemple, plus de 67 millions de codes, et peut supporter des conditions difficiles. Ledit élément (8) peut être utilisé dans toute application exigeant un tri, un marquage, un suivi ou une identification, et peut être formé, si nécessaire, sur des microbilles à l'échelle micronique, ou sur des macro-éléments plus grands pour des applications de plus grande ampleur. Le code peut être un code binaire numérique ou peut être fondé sur d'autres bases numériques.
