The authenticity feature to be examined diffracts the beam of the illumination source and projects it on an evaluation unit in the device. The diffraction pattern derived from the document to be examined is projected onto a projection surface, thereby allowing its evaluation irrespective of the kind and location of the diffraction pattern to be evaluated. The projected diffraction image is detected by a camera (matrix or line scan) and evaluated.

[Arnim Franz-Burgholz, Roland Gutmann, Harald Hoeppner, Thomas Löer, Detlef Märtens, Günther Dausmann, Zishao Yang, Robert Massen, Thomas Franz, Thomas Leitner, Jörg Eberhardt] DE Berlin An apparatus for evaluating distinguishing authenticity features comprising diffraction elements on a document which is illuminated by an illumination source. The distinguishing authenticity element which is to be examined, diffracts the beam of the illuminating source and projects it onto an evaluating unit in the device. In order to be independent of the nature and location of the diffraction pattern, the diffraction pattern derived from the document to be examined is projected onto a screen and the image of the pattern recorded and evaluated by a camera (matrix or cells).

The surface (141) facing the core layer, on the layer directly adjacent to the core layer, has a roughness (19), before lamination to the core layer, which affects the wavelength shift of the image reconstructed by the volume hologram.
