METHOD OF PREPARING AN OPTICALLY VARIABLE IMAGE DEVICE

Optically variable image device assuming the form of a planar optical structure (950), which comprises at least one planar primary area (951) including micro or nano optical primitives or their sets forming said primary area (951) of the planar optical structure (950), arranged such that an impingin...

Zusammenfassung:	Optically variable image device assuming the form of a planar optical structure (950), which comprises at least one planar primary area (951) including micro or nano optical primitives or their sets forming said primary area (951) of the planar optical structure (950), arranged such that an impinging light by interacting with said planar optical structure (950) creates a visual perception of one image (903) corresponding to a characteristic pattern of the respective combination of said three-dimensional phyllotactic model (905) and said core model (906) and, simultaneously, a different visual perception of another image (904) or images corresponding to said graphic pattern (902). A method of preparing such optically variable image device is described as well.
