    Abstract: A multilayer body includes a transparent first layer. In the transparent first layer, a multiplicity of microlenses arranged in accordance with a microlens grid are impressed in a first region. Furthermore, the multilayer body includes a second layer, which is arranged below the first layer and in a fixed position with respect to the first layer and has a multiplicity of microimages arranged in accordance with a microimage grid and in each case in an at least regional overlap with one of the microlenses of the microlens grid for the purpose of generating a first optically variable information item. The grid pitches of the microimage grid and of the microlens grid in each case in at least one spatial direction are less than 300 μm.

    Abstract: A method for producing security elements, security elements, a security document with at least one security element as well as a transfer film with at least one security element wherein a three-dimensional object is recorded and a surface profile of the three-dimensional object, described by a function F(x,y), is determined, wherein the function F(x,y) describes the distance between the surface profile and a two-dimensional reference surface spanned by co-ordinate axes x and y at the co-ordinate points x and y. A first microstructure is determined in such a way that the structure height of the first microstructure is limited to a predetermined value smaller than the maximum distance between the surface profile and the two-dimensional reference surface, and the first microstructure provides an observer with a first optical perception which corresponds to the surface profile of the three-dimensional object described by the function F(x,y).

    Abstract: A multilayer body with a carrier and a layer arranged thereon which comprises electrically conductive material in such an arrangement comprises an information area and a background area (18) which are galvanically separated from each other. In each information area a first zone (10) with electrically conductive material is provided, over the entirety of which electrically conductive material is conductively connected to it. In each background area a plurality of second zones with electrically conductive material is provided, which are galvanically separated from each other. Each first zone (10) preferably occupies a surface area that is at least five times larger than each of the second zones. The electrically conductive material is preferably provided with an average surface coverage which varies over all information areas and background areas (18) by less than 25%. A homogeneous appearance of the multilayer body is thereby ensured, and an item of information provided in the information area, provided by the shape, size and/or alignment of the first zone, is not visible without aids, and therefore cannot be copied.

    Abstract: The invention relates to a method for inspecting a security document (10), the use of an augmented reality system (20) for inspecting a security document (10) as well as an augmented reality system (20). One or more first items of information of the security document (10) are captured by means of an augmented reality system (20), in particular a pair of smartglasses. The one or more first items of information are then checked by comparison with a database (40). Furthermore, one or more of the results of the check of the one or more first items of information are stored and/or one or more of the results of the check of the one or more first items of information are output by means of the augmented reality system (20).
