PATENTAMT.PATENT OFFICE.
Es ist bei gewöhnlichen Kameras an sich bekannt, die durch Schrägsstellung einer ebenen Fläche gegen die Objektivachse entstehende Verzeichnung auf der lichtempfindlichen Platte dadurch aufzuheben, daß der Platte gleichfalls eine Schrägstellung zur optischen Achse gegeben wird. Bei Stereoskopaufnahmen mit Hilfe eines einzigen Objektivs mit Prismen oder Spiegelansatz ist diese SchrägstellungIt is known per se in ordinary cameras that by inclining a flat Area against the lens axis resulting distortion on the photosensitive plate to be canceled by the fact that the plate is also inclined to the optical axis is given. For stereoscopic recordings using a single lens with prisms or mirror approach is this inclination
ίο nicht ohne weiteres zu ermöglichen, da die durch das optische System (Prisma -|- Objektiv) hindurchgehenden Mittelstrahlen senkrecht auf den Ebenen der beiden Teilplatten stehen müssen. Dies wird nach der Erfindung durch eine Kassette erreicht, bei welcher die den beiden Teilbildern entsprechenden Platten einen solchen Winkel zueinander haben, daß die Plattenebenen zu den Mittelstrahlen senkrecht stehen.ίο not readily allow because the Central rays passing through the optical system (prism | lens) perpendicularly must be on the same level as the two sub-panels. This is done according to the invention reaches a cassette in which the plates corresponding to the two partial images are one have such an angle to one another that the plate planes are perpendicular to the central rays stand.
Auf der Zeichnung zeigt Fig. 1 schematisch den Gang der Lichtstrahlen durch das optische System und die Stellung der Platten in der Kassette. Die Stellung der Platten in der gewöhnlichen Kassette wird durch die Linie x-y angedeutet. Damit die Mittelstrahlen senkrecht zur Ebene der Teilplatten mn, op stehen, sind diese mit ihren Außenrändern m und -p nach dem Objektiv zu verschoben. Fig. 2 gibt eine schaubildliche Ansicht der Kassette und zeigt die Lage der Platten in ihr. Die Kassette wird mit dem geraden Teil an der Hinterwand der Kamera in der üblichen Weise befestigt. In der Kassette stehen die Außenränder der Platten dicht hinter dem Kassettenschieber, während die aneinanderstoßenden Innenränder der Platten nach außen verschoben sind. Die Größe der Schrägstellung hängt von dem durch das optische System bedingten Verlauf der Mittelstrahlen ab.In the drawing, FIG. 1 shows schematically the path of the light rays through the optical system and the position of the disks in the cassette. The position of the plates in the usual cassette is indicated by the line xy . So that the central rays are perpendicular to the plane of the partial plates mn, op , they are shifted with their outer edges m and -p towards the objective. Figure 2 is a perspective view of the cassette showing the location of the disks in it. The straight part of the cassette is attached to the rear wall of the camera in the usual way. In the cassette, the outer edges of the plates are close behind the cassette slide, while the abutting inner edges of the plates are shifted outwards. The size of the inclination depends on the course of the central rays caused by the optical system.
