Abstract

Die Erfindung betrifft eine Anzeigevorrichtung zur Darstellung von zweidimensionalen und/oder dreidimensionalen Szenen. Die Anzeigevorrichtung weist wenigstens eine Beleuchtungseinrichtung zum Aussenden von hinreichend kohärentem Licht, wenigstens eine räumlichen Lichtmodulationseinrichtung, wenigstens ein optisches System und eine Nachführeinrichtung auf. In die wenigstens eine räumliche Lichtmodulationseinrichtung ist mittels einer Einzel-Parallaxe-Kodierung ein Hologramm kodiert. Das wenigstens eine optische System ist zur Erzeugung wenigstens eines virtuellen Sichtbarkeitsbereich am Ort eines Auges eines Betrachters vorgesehen. Mittels der Nachführeinrichtung ist die Kodierungsrichtung des Hologramms auf der räumlichen Lichtmodulationseinrichtung veränderbar.
