Abstract (en)
[origin: WO2009000530A2] The invention relates to a security element for security papers, value documents and the like, comprising a microoptical magnification system (30) of the moiré type for representing a three-dimensional moiré image (40) containing image components (42, 44) interspaced in one direction at a right angle to the moiré magnification system in at least two moiré image planes; a motif image that contains two or more periodic or at least locally periodic grid cell arrangements having different grid spacings and/or different grid orientations, that are associated with a respective moiré image plane and that contain micro-motif image components for representing the image component (42, 44) of the associated moiré image plane, a focusing element grid, interspaced from the motif image, for the moiré-magnified viewing of the motif image, comprising a periodic or at least locally periodic arrangement of a plurality of grid cells having respective mcirofocusing elements, the magnified, three-dimensional moiré image (40) moving, when the security element is tilted, in a moiré direction of movement (formula II)) for almost any direction of tilting (formula I)).
