摘要 |
The invention relates to an apparatus for examining documents, in particular documents of value, identification or security documents, having at least two detector units (1, 2, 3) for detecting light (16) emanating from a document (10) to be examined. To increase reliability when examining luminescence, reflection and/or transmission properties of documents, a scattering element (5) is provided on which the light (16) emanating from the document (10) is scattered, the scattering element (5) and detector units (1, 2, 3) being disposed such that the scattered light can be detected by the detector units (1, 2, 3). The scattering element (5) causes spatial mixture and homogenization of the light (16) emanating from the document (10) so as to greatly reduce any parallactic errors that occur in particular with detector units (1, 2, 3) disposed side by side.
