Abstract

Die Erfindung betrifft ein Verfahren zum Berechnen eines computergenerierten Hologramms, bei dem die Punkteverteilung des computergenerierten Hologramms berechnet wird, bei dem die Punkteverteilung einer makroskopischen Überstruktur berechnet wird und bei dem die Punkteverteilung mindestens eines computergenerierten Hologramms mit der Punkteverteilung der makroskopischen Überstruktur zu einer in einem Speichermedium zu schreibenden Punkteverteilung verknüpft wird. Ebenso betrifft die Erfindung ein Verfahren zum Schreiben des Hologramms, ein Speichermedium sowie eine Lesevorrichtung. Daher können sowohl ein computergeneriertes Hologramm als auch eine makroskopische Überstruktur, die direkt lesbare Informationen enthalten kann, in einer Punkteverteilung zusammengeführt werden.
