Abstract

L'invention concerne un dispositif de sécurité incluant un substrat ou un ou plusieurs éléments de focalisation ou structures de lentilles situés sur une face du substrat. Le dispositif de sécurité inclut une pluralité d'éléments d'image associés à chaque élément de focalisation, lesdits éléments d'image comprenant au moins un premier et un deuxième groupes d'éléments d'image. Chaque élément d'image peut être composé de pixels situés dans un plan d'objet de façon à être visibles à travers l'élément de focalisation associé. Chaque élément d'image comprend un élément de réseau diffractif ou un élément de réseau sub-longueur d'onde qui, lorsqu'il est éclairé par une source de lumière, génère une image de diffraction observable selon une plage d'angles de vue autour du dispositif. Les éléments d'image d'un premier groupe sont visibles selon une première plage d'angles de vue et les éléments d'image d'un deuxième groupe sont visibles selon une deuxième plage d'angles de vue. Le dispositif de sécurité est particulièrement approprié pour être utilisé sur des documents de sécurité, tels que des billets de banque. Un procédé de fabrication d'un dispositif de sécurité est également décrit.
