Abstract
(FR) La présente invention concerne un dispositif optiquement variable pour produire un effet visuel tridimensionnel, le dispositif optiquement variable incluant au moins deux couches, une première couche incluant un premier motif et une deuxième couche incluant un deuxième motif, la deuxième couche étant séparée de la première couche d'une certaine distance et le deuxième motif incluant au moins une région qui est une version à échelle modifiée d'une région correspondante du premier motif. Plus particulièrement, l'effet visuel tridimensionnel perçu lorsqu'on regarde le dispositif optiquement variable est observé en raison des interférences de moiré.
