Description

Es ist bereits ein Verfahren der. kinematographischen Kombinationsaufnahrae beschrieben, bei dem der Nebenschauplatz durch Hintergrundprojektion gewonnen wird und der Hintergrund so ausgebildet ist, daß er das Objektiv des Projektionsapparates im Objektiv des Aufnahmeapparates abbildet. Als geeignetstes Mittel hierzu ist ein Hohlspiegel angegeben, der wegen seiner notwendigen Größe aus Ideinen Einzelhohlspiegeln zusammengesetzt ist. Da diese Einzelhohlspiegel lückenlos aneinanderpassen müssen, hat man bisher als das Beste reguläre Sechsecke verwandt. Die genaue Aneinanderpassung dieser Einzelhohlspiegel ist aber mechanisch schwierig, da die Trennungslinien natürlich nicht sichtbar werden dürfen. Die Erfindung bezweckt hierfür eine bedeutende Vereinfachung. Sie erreicht dies dadurch, daß die Einzelhohlspiegel in mehreren dichtIt is already a process of. cinematographic combination recordings described, in which the secondary scene is obtained by background projection and the background is designed in such a way that it The lens of the projection apparatus is imaged in the lens of the recording apparatus. As the most suitable Means for this is given a concave mirror, which because of its necessary size from Ideine Single concave mirror is composed. Because these individual concave mirrors fit together seamlessly so far, regular hexagons have been used as the best. The exact matching of these individual concave mirrors is but mechanically difficult, since the dividing lines must of course not be visible. The invention aims to simplify this significantly. It does this by that the single concave mirror in several tight

ao hintereinanderliegenden konzentrischen Kugelflächen angeordnet sind. Der Anordnung in Sechsecken entspricht hierbei eine dreifache Schicht von Hohlspiegeln. Dabei können die Einzelhohlspiegel kreisförmig sein, was die mechanische Herstellung sehr vereinfacht. Es stoßen dann nicht mehr die scharfen Kanten aneinander, sondern es liegt der Spiegelrand stets vor oder hinter der Fläche eines anderen Spiegels.ao concentric spherical surfaces lying one behind the other are arranged. The arrangement in hexagons corresponds to a three-fold layer of concave mirrors. The Single concave mirror be circular, which greatly simplifies mechanical production. It Then the sharp edges no longer meet, but the mirror edge lies always in front of or behind the surface of another mirror.

Die Abbildungen zeigen schematisch eine Anordnung nach der Erfindung. Nach Abb. 1 ist eine Fläche mit Hohlspiegeln bedeckt. Abb. 2 ist ein Schnitt längs der Linie X-X der Abb. 1. Die Spiegel sind mit den Ziffern 1, 2 und 3 bezeichnet, je nachdem sie in der vorderen, mittleren oder hinteren Fläche liegen. Die Verbindungslinien der Mittelpunkte der in derselben Kugelfläche liegenden, mit denselben Ziffern bezeichneten Spiegel bilden stets gleichseitige Dreiecke. Abb. 2 zeigt die Grundplatte a, an welcher die Spiegel durch Justierschrauben δ und Halteschrauben c befestigt sind. Die Vorderflächen d sind die spiegelnden Flächen, welche durch einen Lacküberzug geschützt sind. Wegen ihres großen Krümmungsradius (von bis 8 m) erscheinen die Spiegel in Abb. 2 eben.The figures show schematically an arrangement according to the invention. According to Fig. 1, a surface is covered with concave mirrors. Fig. 2 is a section along the line XX in Fig. 1. The mirrors are designated with the numbers 1, 2 and 3, depending on whether they are in the front, middle or rear surface. The connecting lines of the center points of the mirrors, which are located in the same spherical surface and denoted by the same numbers, always form equilateral triangles. Fig. 2 shows the base plate a, to which the mirrors are attached by adjusting screws δ and retaining screws c. The front surfaces d are the reflective surfaces which are protected by a lacquer coating. Because of their large radius of curvature (up to 8 m), the mirrors in Fig. 2 appear flat.
