Description

Gegenstand des Hauptpatentes 469413 ist eine Mehrfachkammer für Aufnahmen aus Luftfahrzeugen, bestehend aus mehreren kranzartig um eine mittlere Kammer oder eine Symmetrieachse angeordneten Einzelkammern mit einer gemeinsamen Fokalebene. Der Zweck der Erfindung des Hauptpatentes, nämlich die Erzeugung von Teilaufnahmen auf einen einzigen ebenen Schichtträger, welche sich nach Umformung auf die Richtung der Symmetrieachse, d. h. der optischen Achse der mittleren Aufnahme, zu einem geschlossenen Bild nach Art einer mit einem einzigen Objektiv hergestellten Weitwinkelaufnahme zusammensetzen lassen, wird durch Einschaltung von Prismen mit dreieckigem Querschnitt und je zwei reflektierenden Flächen in den Strahlengang der den Kranz bildenden Kammern erreicht. Diese Prismenanordnung, welche es zwar erlaubt, bei kleinen Dimensionen einen genügend großen Bildwinkel für jede Teilaufnahme zu erzielen, läßt jedoch wenig Spielraum in der Wahl des Ablenkungswinkels für das gesamte Strahlenbündel. Dieser Spielraum reicht z. B. nicht aus, um die Anwendung von Objektiven höchster Lichtstärke oder die im Hauptpatent erwähnte kranzförmige Kammeranordnung ohne, Mittelkammer in befriedigender Weise zu verwirklichen.The subject of main patent 469413 is a multiple chamber for recordings from aircraft, consisting of several in a wreath around a central chamber or an axis of symmetry arranged individual chambers with a common focal plane. The purpose of the invention of the main patent, namely the creation of partial recordings on a single flat substrate, which, after reshaping, is directed towards the axis of symmetry, d. H. the optical axis of the central recording, to a closed one Image similar to a wide-angle photograph taken with a single lens can be put together by the inclusion of prisms with triangular Cross-section and two reflective surfaces each in the beam path of the wreath forming Chambers reached. This prism arrangement, which allows small ones Dimensions to achieve a sufficiently large angle of view for each partial exposure, but leaves little leeway in the choice of the deflection angle for the entire beam. This scope extends z. B. not enough to use lenses with the highest speed or those in the main patent mentioned annular chamber arrangement without realizing the middle chamber in a satisfactory manner.

Die Erfindung bezweckt, diesen geringen Spielraum in der Wahl des Gesamtablenkungswinkels zu erweitern. Sie erreicht dies dadurch, daß die zweite reflektierende Fläche im Innern des Prismenkörpers liegt.The invention aims at this small margin in the choice of the total deflection angle to expand. It achieves this in that the second reflective surface lies in the interior of the prism body.

Die beiliegende Abbildung zeigt eine Ausführungsform der erfindungsgemäßen Vorrichtung in einem durch eine Symmetrieebene geführten Schnitt.The accompanying figure shows an embodiment of the device according to the invention in a section guided through a plane of symmetry.

In einem starren Kammerkörper α sind die den Kranz bildenden Objektive O1 und b% sowie die zugehörigen Prismen ^1, e„ fest montiert. Die Kammer ist durch lichtdichte Zwischenwände f unterteilt. Der Oberteil e der Kammer nimmt den ebenen Schidhtträger d (Platte, Film) auf. Die beiden Prismen ex und e2 sind je durch einen ebenen Luftspalt g1; g2 derart unterteilt, daß eine im Innern des Prismas liegende zweite reflektierende Fläche entsteht. The objectives O 1 and b % , which form the ring, and the associated prisms ^ 1 , e "are firmly mounted in a rigid chamber body α. The chamber is divided by light-tight partition walls f . The upper part e of the chamber accommodates the flat sheet carrier d (plate, film). The two prisms e x and e 2 are each separated by a flat air gap g 1; g 2 subdivided in such a way that a second reflective surface is created inside the prism.
