Abstract

Die Erfindung betrifft eine Vorrichtung und ein entsprechendes Verfahren zur Untersuchung von Dokumenten, insbesondere Wert-, Ausweis- oder Sicherheitsdokumenten, mit mindestens einer Anregungseinrichtung zur Anregung von Lumineszenzlicht (16) in oder auf einem zu untersuchenden Dokument (10) und mindestens zwei Detektoreinheiten (1, 2) zur Erfassung zumindest eines Teils des von dem Dokument (10) emittierten Lumineszenzlichts (16).The invention relates to a device and a corresponding method for the examination of documents, in particular value, identity card or Security documents, with at least one excitation device for Excitation of luminescent light (16) in or on a to be examined Document (10) and at least two detector units (1, 2) for detection at least part of the luminescent light emitted by the document (10) (16).

Zur Erhöhung der Zuverlässigkeit der Untersuchung der spektralen Charakteristik des Lumineszenzlichts (16) ist vorgesehen, daß die Detektoreinheiten (1, 2) bezogen auf das von dem Dokument (10) emittierte Lumineszenzlicht (16) hintereinander angeordnet sind. Hierdurch trifft das Lumineszenzlicht (16) nacheinander auf die Detektoreinheiten (1, 2) und wird dabei von diesen erfaßt.To increase reliability of investigation of spectral characteristics the luminescence light (16) is provided that the detector units (1, 2) based on the luminescent light emitted by the document (10) (16) are arranged one behind the other. As a result, the luminescent light strikes (16) successively on the detector units (1, 2) and is thereby of this detected.

Durch die Erfindung werden etwaige Parallaxenfehler, die besonders bei seitlich versetzter Anordnung der Detektoreinheiten auftreten, stark reduziert, so daß die Detektoreinheiten (1, 2) das von einem gemeinsamen räumlichen Teilbereich (11) des Dokuments (10) emittierte Lumineszenzlicht (16) erfassen können.

Figure 00000001
By means of the invention, any parallax errors which occur particularly in the case of a laterally offset arrangement of the detector units are greatly reduced, so that the detector units (1, 2) can detect the luminescent light (16) emitted by a common spatial subarea (11) of the document (10) ,
