A special visual effect is achieved. An optical device (1) includes a light-reflecting interface provided with a first relief structure including first recesses or protrusions arranged two-dimensionally, the first relief structure emitting a first diffracted light when illuminated with a light, and a light--transmitting interface disposed in front of the light--reflecting interface and having a reflectance smaller than that of the first interface, the light--transmitting interface being provided with a second relief structure including second recesses or protrusions arranged two-dimensionally, and the second relief structure emitting a second diffracted light when illuminated with the light.

Des effets spéciaux visuels sont obtenus. Un élément optique (1) comprend une interface de réflexion de la lumière et une interface de transmission de la lumière. L'interface de réflexion de la lumière comporte une première structure en relief qui comprend une pluralité de premières sections creusées ou saillantes conçues en deux dimensions, et la première structure en relief émet une première lumière diffractée lorsqu'elle est exposée à la lumière. L'interface de transmission de la lumière est disposée à l'avant de l'interface de réflexion de la lumière, sa réflectance étant inférieure à celle de la première interface, et présente une seconde structure en relief qui comprend une pluralité de parties creusées ou saillantes conçues en deux dimensions. La seconde structure en relief émet une seconde lumière diffractée lorsqu'elle est exposée à la lumière.
