Abstract
Die Erfindung betrifft eine Anordnung zur Bilderzeugung, bevorzugt zur Verwendung in Fernsehgeräten und Projektoren, die nach den Prinzipien der Rück- und Frontprojektion arbeiten, umfassend eine Beleuchtungseinrichtung, einen Farbmodulator, ein bilderzeugendes Element mit Kippspiegelelementen (DMD) (2) sowie einer Projektionsoptik (5), wobei der von der Beleuchtungseinheit ausgehende Lichtanteil (LB) vom DMD (2) reflektiert wird und der zum Bildaufbau beitragende Lichtanteil (LP) über die Projektionsoptik (5) in die Bildebene gelangt. DOLLAR A Erfindungsgemäß ist im Projektionsstrahlengang (LP) ein um eine Kippachse (K) schwingfähiger Umlenkspiegel (6) vorgesehen, der mit zum Zwecke der Zuführung der Schwingbewegung dienenden Antriebselementen (8, 9) in Verbindung steht.
