Abstract

Um eine brennpunktorientierte Blende (100) anzugeben, welche insbesondere für hochenergetische Strahlung vorgesehen ist und welche ein schnelles Versetzen der Richtung eines Strahles, welcher durch einen Brennpunkt verläuft, ermöglicht, ist vorgesehen, dass ein Absorptionselement (10) eine periodische Bewegung ausführen kann und derart geformt ist, dass in jeder während der periodischen Bewegung eingenommenen Lage höchstens eine Richtung (18) existiert mit der Eigenschaft, dass Strahlung, insbesondere Strahlung einer bestimmten Strahlart, welche auf einem durch einen Brennpunkt (16) verlaufenden Strahl auf die brennpunktorientierte Blende (100) fällt, im Wesentlichen durchgelassen wird, wenn der Strahl im Wesentlichen in besagter Richtung (18) verläuft, und sonst im Wesentlichen absorbiert wird.
