    摘要: A security device for improving the security against falsification of articles has a carrier element (10). Arranged on the upper side of the carrier element (10) are a large number of diffractive surface elements (18). The surface elements (18) 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 (28) 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.

    摘要: The invention relates to an optical security device (1, 1'), comprising a carrier (5) and a plurality of planar elements (8, 8a, 8b, 8c, 18a, 18b, 18c), which are distributed on a surface of the carrier (5) and which have a first diffractive element, wherein the first diffractive element has a structure that periodically repeats in a first direction, wherein the planar elements (8, 8a, 8b, 8c, 18a, 18b, 18c) having the first diffractive element form a plurality of groups each having at least two planar elements (8, 8a, 8b, 8c, 18a, 18b, 18c), wherein the planar elements (8, 8a, 8b, 8c, 18a, 18b, 18c) having the first diffractive element of each group are arranged and designed in such a way that the first diffractive elements produce a pixel of a first image (13, 14) for an observer (3) or an observation apparatus, wherein the first image (13, 14) is composed of the pixels produced by the plurality of groups, wherein the planar elements (8, 8a, 8b, 8c, 18a, 18b, 18c) are arranged and designed in such a way that, during operation of the security device (1, 1'), the number of planar elements (8, 8a, 8b, 8c, 18a, 18b, 18c) of a group that produce a pixel of the first image (13, 14) or the planar elements (8, 8a, 8b, 8c, 18a, 18b, 18c) of the group that are involved in the production of the pixel depend on an angle of incidence (α) at which light from a light source (2) hits the security device (1, 1') or on an angle of observation (β) at which the observer (3) or the observation apparatus observes the security device (1, 1'), and wherein the planar elements (8, 8a, 8b, 8c, 18a, 18b, 18c) are arranged and designed in such a way that, during the operation of the security device (1, 1'), a position of the first image (13, 14) in an observation space (15) for the observer (3) or the observation device depends on the angle of incidence (α) or the angle of observation (β). According to the invention, in order to provide an optical security device that has a higher degree of design freedom in the selection of the displayed images, at least one planar element (8, 8a, 8b, 8c, 18a, 18b, 18c) has, in addition to the first diffractive element, a second diffractive element having a structure that periodically repeats in a second direction, wherein the first direction and the second direction are different from each other.

    摘要: The invention relates to a security device for improving the security against the falsification of articles, having a support element (10). A plurality of diffractive surface elements (18) are arranged on the surface of the support element (10). Each surface element (18) forms multiple surface element groups, the surface structures of which match one another so as to make precisely one point (28) of the corresponding symbol to be displayed visible to an observer under specified viewing conditions. By changing the angle of incidence of the light and/or the angle of observation of the observer, a continuous movement of the at least one symbol is perceived by the observer.
