Abstract

Die Erfindung betrifft eine Vorrichtung zur Untersuchung von Dokumenten, insbesondere Wert-, Ausweis- oder Sicherheitsdokumenten, mit mindestens zwei Detektoreinheiten (1, 2, 3) zur Erfassung von Licht (16), welches von einem zu untersuchenden Dokument (10) ausgeht.The invention relates to a device for examining documents, in particular value, identity or security documents, with at least two detector units (1, 2, 3) for detecting light (16) generated by a document under examination (10).

Zur Erhöhung der Zuverlässigkeit bei der Untersuchung der Lumineszenz-, Reflexions- und/oder Transmissionseigenschaften von Dokumenten ist ein Streuelement (5) vorgesehen, an welchem das von dem Dokument (10) ausgehende Licht (16) gestreut wird, wobei das Streuelement (5) und die Detektoreinheiten (1, 2, 3) so angeordnet sind, daß das gestreute Licht von den Detektoreinheiten (1, 2, 3) erfaßt werden kann.To increase the reliability in the investigation of luminescence, Reflection and / or transmission properties of documents is a Scattering (5) provided on which the document (10) outgoing Light (16) is scattered, wherein the scattering element (5) and the detector units (1, 2, 3) are arranged so that the scattered light from the detector units (1, 2, 3) can be detected.

Durch das Streuelement (5) wird eine räumliche Mischung und Homogenisierung des von dem Dokument (10) ausgehenden Lichts (16) bewirkt, so daß etwaige Parallaxenfehler, die insbesondere bei nebeneinander angeordneten Detektoreinheiten (1, 2, 3) auftreten, stark verringert werden.

Figure 00000001
The scattering element (5) effects a spatial mixing and homogenization of the light (16) emanating from the document (10), so that any parallax errors which occur, in particular, in the case of detector units (1, 2, 3) arranged side by side are greatly reduced.
