摘要： A security device for improving the security against falsification of articles has a carrier element. Arranged on the upper side of the carrier element are a large number of diffractive surface elements. The surface elements respectively form a number of surface element groups, surface structures of which are made to match one another in such a way that they show a point of the symbol to be represented over an entire observation sphere. By changing the angle of incidence of the light and/or the angle of observation of an observer, a continuous movement of the symbol in the observation sphere is perceived by the observer.
