Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Erkennung gefälschter Wertdokumente, bei dem die Wertdokumente mit getaktetem Anregungslicht einer Lichtquelle beleuchtet werden. Innerhalb der Hellphase des Anregungslichts wird eine erste Lumineszenzintensität erfasst, innerhalb der Dunkelphase eine zweite Lumineszenzintensität. Aufgrund des Nachleuchtens der Lichtpulse ergibt sich eine Restfluoreszenz, die die Lumineszenzintensität in der Dunkelphase verfälscht. Durch Verknüpfen der zweiten Lumineszenzintensität mit der ersten Lumineszenzintensität, z.B. durch Subtraktion einer skalierten ersten Lumineszenzintensität, wird eine korrigierte zweite Lumineszenzintensität bestimmt, die im Wesentlichen dem Phosphoreszenzsignal des Wertdokuments entspricht.
