57	Abstract	AB	Es wird ein akusto-optisches Filterelement (114) vorgeschlagen, welches einen akusto-optischen Kristall (118) mit einem akustischen Signalgeber (120) zur Erzeugung akustischer Signale in dem akusto-optischen Kristall (118) aufweist. Der akusto-optische Kristall (118) ist eingerichtet, um entsprechend einer an den akustischen Signalgeber (120) applizierten Hochfrequenz selektiv Licht einer Zielwellenlänge aus einem in den akusto-optischen Kristall (118) eintretenden Eingangslichtstrahl (116) räumlich abzulenken und einen Ziellichtstrahl (126) mit der Zielwellenlänge zu erzeugen. Weiterhin umfasst das akusto-optische Filterelement (114) ein in dem Ziellichtstrahl (126) angeordnetes Raumfilterelement (132), welches ausgestaltet ist, um in eine Ebene senkrecht zur Ausbreitungsrichtung des Ziellichtstrahls (126) selektiv die Intensität des Ziellichtstrahls (126) zu unterdrücken.
