Description

Optisches System zum l:@zue plastischer Lichtbilder . .. Optische Systeme, die aus zwei Objektiven und je seinem zu deren 'optischen Achsen unter 45' geneigten Spiegel bestehen, von denen der eine Spiegel teilweise lichtdurchlässig ist und die so. zueinander angeordnet sind, daß sich die erzeugten Einzelbilder zur Deckung bringen lassen, sind bereits bekannt. Bei einer derartigen Vorrichtung mit @so angeordneten Obj ektiven, daß deren optischetAchsen stets parallel zueinander verlaufen, wandern bei Annäherung des Objekts die Einzelbilder seitlich aus und befinden sich, wenn sie bei weit entferntem Objekt in Deckung waren, nun nicht mehr in Deckung. Durch das bekannte Schwenken des einen Spiegels läßt sich zwar das Zusammenfallen der Bildmitten erreichen, doch es lä:ßt sieh hierbei nicht vermeiden, daß die Bildebenen um die Bildmitten gegeneinander so stark verschwenkt sind, daß an denn. Bildrändern störende Unschärfen auftauchen. Auch ist die auftretende Parallaxe bei dieser Anordnung sehr groß. Diese Mängel lassen sich dadurch auf ein praktisch zulässiges Maß beseitigen und für die Bildwirkung sogar nutzbar machen, daß bei einem optischen System der :eingangs angegebenen Art gemäß der Erfindung das reine der beiden Objektive um den Mittelpunkt des von ihm ohne den zugehörigen Spiegel erzeugten Bildes schwenkbar gelagert ist.Optical system for the l: @zue of three-dimensional light images. .. Optical Systems that consist of two lenses and each its to their 'optical axes under 45 'inclined mirrors consist of which one mirror is partially translucent is and the so. are arranged to each other that the generated individual images can be brought to congruence are already known. In such a device with lenses arranged in such a way that their optical axes are always parallel to each other run, the individual images migrate to the side as the object approaches are no longer in cover if they were in cover when the object was far away for cover. By the known pivoting of one mirror, it is true that the collapse reach the center of the picture, but it cannot be avoided that the picture planes are so strongly pivoted against each other around the image centers that on then. Image edges disturbing blurring appear. Also the occurring parallax is with this arrangement very large. These deficiencies can thereby be eliminated to a practically permissible level and even make it useful for the image effect that in an optical system the : initially specified type according to the invention, the pure of the two lenses around the center of the image generated by him without the associated mirror can be pivoted is stored.

In der Zeichnung ist der Erfindungsgegenstand in -einer beispielsweisen Ausführungsform schematisch dargestellt.In the drawing, the subject of the invention is an example Embodiment shown schematically.

A und C sind die beiden Objektive. a und b sind die leiden Spiegel, die unter sich parallel, ,aber zu, den Systemachsen A-B bzw. C-D unter q.5° geneigt liegen. Der Spiegela ist vorn normaler Ausführung, während der Spiegel b in an sich. bekannter Weise; teilweise lichtdurchlässig ist. c äst die Mattscheibe bzw. der lichtempfmdliahe Schichtträger. Die Brennweiten der Objektive A und C sind gleich.A and C are the two lenses. a and b are the suffering mirrors, which are parallel to each other, but inclined to the system axes A-B and C-D at q.5 ° lie. The mirror a is in front of normal execution, while the mirror b in itself. known way; is partially translucent. c eats the ground glass or the light-sensitive support. The focal lengths of lenses A and C are the same.

Gemäß der Erfindung ist z. B. nun das Objektiv C um den Mittelpunkt des von ihm ohne den zugehörenden Spiegel b erzeugten Bildes schwenkbar gelagert, während das andere ObjektivA feststehend angeordnet ist.According to the invention, for. B. now the lens C around the center the image generated by it without the associated mirror b is pivoted, while the other lens A is fixed.

Die beiden Systemachsen A-B und C-D verlaufen bei Aufnahme weit entfernter Objekte parallel. Soll nun sein nahe in Achserrichtung des Objektivs A liegender Gegenstand aufgenommen werden, - so wird das Objektiv C um seinen Brennpunkt d nach denn Objektiv A zu so lange geschwenkt, bis die Bilder der beiden Objektive auf der Mattscheibe c zusammenfallen.The two system axes AB and CD run parallel when recording objects that are far away. Will now be obvious in axis direction of the lens A subject are taken, - that the lens C is at its focus to d for lens A pivoted to as long c coincide on the screen until the images of both lenses.

Die Scharfeinstellung .erfolgt in bekannter Weise entweder durch gemeinsames Verschicben der Objektive A und C oder durch Verschieben des Rahmens der Mattscheibe bzw. des Schichtträgers c.The focusing. Takes place in a known manner either by joint Moving the lenses A and C or by moving the frame of the focusing screen or of the substrate c.
