Abstract

Die Erfindung betrifft ein optisches Sicherheitselement sowie ein System zur Visualisierung von versteckten Informationen mit einem derartigen optischen Sicherheitselement. Das optische Sicherheitselement weist eine Substratschicht auf, in der in einem von einer X- und einer Y-Achse aufgespannten Flächenbereich eine durch Reliefparameter, insbesondere Reliefform, Relieftiefe, Spatialfrequenz und Azimutwinkel, definierte Reliefstruktur zur Erzeugung eines optisch erkennbaren Effektes abgeformt ist. Ein oder mehrere der die Reliefstruktur definierenden Reliefparameter sind in dem Flächenbereich (27) gemäss einer Parameter-Variations- Funktion variiert. Der Flächenbereich (27) ist in ein oder mehrere Musterbereiche (29, 30) und einen Hintergrundbereich (28) geteilt. Ein oder mehrere der die Reliefstruktur definierenden Reliefparameter sind in den ein oder mehreren Musterbereichen (29, 30) gemäss einer gegenüber der Parameter-Variations-Funktion des Hintergrundbereiches (28) phasenverschobenen Parameter-Variations-Funktion variiert. Weiter ist ein Verifikationselement vorgesehen, das ein durch eine periodische Transmissions-Funktion definiertes Verifikationsraster besitzt, dessen Periode der Periode der Parameter-Variations-Funktion entspricht.
