Abstract

L'invention concerne un modèle de surface variable sur le plan optique, muni de structures de diffraction de la lumière, qui comprend un arrière-plan (8) et une information image (9) figurant sur ledit arrière-plan (9). Dans des conditions normales d'éclairage, la lumière incidente sur l'arrière-plan (9) et l'information image (9) est diffractée dans différentes directions, de sorte à permettre à un observateur de lire ladite information. Les structures de diffraction de la lumière formant l'arrière-plan (8), de même que l'information image (9) se présentent de manière à placer toutes, lors de la reproduction à l'aide d'une photocopieuse couleur, les photodiodes en saturation, de sorte à faire apparaître sur la photocopie, une surface claire sans contraste, à la place de l'arrière-plan (8) muni de l'information image (9). Les structures de diffraction utilisées sont notamment des structures mates.
