摘要： 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).

摘要： A document-examining apparatus is provided for automatically examining the authenticity elements of secured documents. It includes a compound slide which can be moved in the X and Y directions and on which the components required to evaluate the distinguishing authenticity features are mounted. The X slide of the compound slide is mounted on a Y slide. A first group of evaluating units for evaluating diffraction elements on a document is disposed on the X slide. A second group of evaluating components, for example, for evaluating text, an IR field and/or a photographic field, may be mounted on the Y slide. In addition, a source of UV radiation may be provided for examining distinguishing fluorescence features of a document, the fluorescence being evaluated by a stationary evaluating unit or by the evaluating unit on the X slide.
