Abstract

Die Erfindung betrifft eine holographische Anzeigevorrichtung zur Darstellung einer zweidimensionalen und/oder dreidimensionalen Szene. Die holographische Anzeigevorrichtung weist wenigstens eine räumliche Lichtmodulationseinrichtung (4) und ein optisches Bauteil (8) auf. Die wenigstens eine räumliche Lichtmodulationseinrichtung (4) ist zur Rekonstruktion der Szene und zur Erzeugung wenigstens eines virtuellen Sichtbarkeitsbereichs (5) in einer Betrachterebene (6) vorgesehen. Das optische Bauteil (8) ist mit wenigstens zwei Bereichen (8-1, 8-2) ausgebildet, die eine unterschiedliche Transparenz zueinander aufweisen, wobei der Wert der Transparenz jeweils zwischen 0 und 1 liegt. Zudem ist das optische Bauteil (8) derart in der Anzeigevorrichtung angeordnet, dass es eine wenigstens teilweise vorzunehmende Filterung eines Gleichanteil-Spots in wenigstens einer Beugungsordnung innerhalb des virtuellen Sichtbarkeitsbereichs vorsieht.
