Vorrichtung zur Ablenkung eines parallelen Lichtbündels.Device for deflecting a parallel light beam.

Beschreibung Gegenstand der Erfindung i.st einc Vorrichtung zur Ablenkung eines als Radiusvektor um einen Drehpunkt kreisenden parallelen Lichbündels aus der durch diese Kreisbewegung beschriebenen Kreisfläche derart, daß das Lichtbündel in bestimmtem Abstand von der Normalen auf den Kreismittelpunkt eine Schraubenlinie beschreibt.Description of the subject matter of the invention is a device for deflection a parallel bundle of light circling around a fulcrum as a radius vector the circular surface described by this circular movement in such a way that the light beam a helical line at a certain distance from the normal to the center of the circle describes.

Wenn auf dieser Schraubenlinie auf einer Zylinderinnenfläche die Lichteintrittsenden von Lichtleitfasern angeordnet werdcn, dann kann mit dieser Anordnung ein Bildschirm mit günstigem Verhältnis von eildflächí. zu Bautiefe realisiert werden.When the light entry ends on this helical line on an inner surface of the cylinder are arranged by optical fibers, then with this arrangement a screen with a favorable ratio of eildflächení. to be realized in depth.

Es ist vorgeschlagen werden, daß ein Drehspiegel, der die Kreisbewegung des parallelen Lichtbündels um einen Drehpunkt durch Rotation um die Lichteinfallsachse erzeugt, das Lichtbündel dadurch eine Schraubenlinie in bestimmtem Abstand von der Drehaschse beschreiben läßt, daß der Spiegel in Achsrichtung bewegt wird. It is proposed that a rotating mirror that makes the circular motion of the parallel light beam around a fulcrum by rotating around the axis of incidence of light generated, the light beam creates a helix at a certain distance from the The axis of rotation describes that the mirror is moved in the axial direction.

Es ist konstruktiv schwierig, ein rotierendes Teil auch noch axial kontrolliert zu bewegen. @er erfindung liegt die Aufgabe zugrunde, die axiale Bewegung des Spiegels zu vermeiden.It is structurally difficult to have a rotating part also axially to move in a controlled manner. @ The invention is based on the task of the axial movement to avoid the mirror.

Die axiale Ablenkung des kreisenden Lichtstrahles mit dem Zweck, eine Schraubenlinie zu schreiben, geschieht dadurch, daß ein ringrörmiger, rotationssymmetrischer Keil aus lichtbrechendem Material, dessen Symmetrieachse parallel mit der Spiegeldrehachse ist, und den das Lichtbündel durchqueren muß, in Achsrichtung bewegt wird.The axial deflection of the circling light beam with the purpose of a Writing a helix is done by creating an annular, rotationally symmetrical Wedge made of refractive material, the axis of symmetry of which is parallel to the axis of rotation of the mirror is, and which the light beam must traverse, is moved in the axial direction.

In der Abbildung ist die Erfindung dargestellt. Ein axial auf den rotierenden Spiegel 1 fallendes Lichtbündel wird durch den axialbeweglichen Ringkeil 2) so abgelenkt, daß er auf einer Zylinderinnenfläche 3 eine Schraubenlinie schreibt.In the figure the invention is shown. One axially on the rotating mirror 1 falling light beam is caused by the axially movable ring wedge 2) deflected so that it writes a helix on an inner surface 3 of the cylinder.
