Abstract

Image personnalisée formée à partir d’une couche métallique et d’un réseau lenticulaire L’invention vise notamment un document sécurisé (10) comprenant : une couche métallique (14) comportant un arrangement de nanostructures diffractives; un réseau lenticulaire (12) comprenant des lentilles convergentes (13) positionnées en regard de la couche métallique ; et une couche support (16) sur laquelle est disposée la couche métallique de sorte à ce que la couche métallique (14) soit intercalée entre le réseau lenticulaire (12) et la couche support (16). La couche métallique comprend des perforations (20) formées par focalisation d’un rayonnement laser (RY) au travers du réseau lenticulaire sur la couche métallique (14), les perforations comprenant au moins un groupe de perforations (RY) réalisées par focalisation du rayonnement laser (RY) suivant un angle d’incidence (θ) respectif de sorte à révéler une image personnalisée (IG) correspondante lorsque le document sécurisé est observé suivant ledit angle d’incidence. Figure pour l’abrégé : Fig. 4.
