Description

Verfahren zum seitenrichtigen optischen Kopieren von Linsenrasterfilmen auf ebensolche Filme Im Hauptpatent wird ein Verfahren zum seitenrichtigen optischen Kopieren von Linsenrasterfilmen auf ebensolche Filme unter Beleuchtung des Negativfilms von der Rasterseite her unter Schutz gestellt. Die Beleuchtung erfolgt hierbei in der Weise, daß eine leuchtende Ebene auf dem Negativfilm abgebildet wird. Da bei dieser Art der Beleuchtung infolge der Linsenrasterung des Negativfilms sich überdeckende Interferenzbilder der Aufnahmefilterebene entstehen, wird in einer besonderen Ausführungsform des Verfahrens an der dem Aufnahmefilter entsprechenden Stelle des Beleuchtungsobjektivs eine Blende in Form eines im spitzen Winkel zur Richtung der Zylinderlinsen des Negativfilms verlaufenden Spaltes angeordnet, dessen Breite so bemessen ist, daß die infolge der Linsenrasterung von den Zylinderlinsen entworfenen Interferenzbilder sich nicht überdecken.Method for the correct reading of optical copies of lenticular films on films of this kind Copying of lenticular films on films of the same type with illumination of the negative film placed under protection from the grid side. The lighting is done in such that a luminous plane is imaged on the negative film. Included this type of illumination as a result of the lenticular rastering of the negative film overlapping Interference images of the recording filter plane are created in a special embodiment of the method at the point of the illumination lens corresponding to the recording filter a diaphragm in the form of an at an acute angle to the direction of the cylinder lenses Negative film arranged extending gap, the width is such that the interference images created by the cylindrical lenses as a result of the lenticular rasterization do not overlap.

Erfindungsgemäß wird diese Anordnung dadurch vereinfacht, daß man den Film mit einer Vorrichtung beleuchtet, deren leuchtende Fläche der im Hauptpatent durch die Spaltblende herausgeschnittenen Leuchtfläche entspricht. Man ersetzt zu diesem Zweck die leuchtende Fläche durch einen dünnen Glühfaden, der im spitzen Winkel zur Richtung der Zylinderlinsen des Negativfilms verläuft und so breit bemessen ist, daß keine sich überdeckenden Interferenzbilder entstehen. Man erreicht also durch die fadenförmige Leuchtquelle in einfacherer und billigerer Weise die gleiche Wirkung wie durch die Verbindung einer leuchtenden Fläche mit einer Spaltblende.According to the invention this arrangement is simplified in that one illuminates the film with a device whose luminous surface is that in the main patent corresponds to the luminous surface cut out through the slit diaphragm. One replaces too For this purpose, the luminous surface through a thin filament that is pointed in the Angle to the direction of the cylinder lenses of the negative film and dimensioned as wide is that no overlapping interference images arise. So one achieves the same in a simpler and cheaper way thanks to the thread-like light source Effect like the connection of a luminous surface with a slit screen.

Der Ersatz eines leuchtenden Spaltes durch eine fadenförmige Lichtquelle ist an sich bekannt, jedoch in der vorliegenden Verwendung in bestimmter Breite und bestimmter Stellung zur Linienrasterung ist er neu.The replacement of a glowing gap with a thread-like light source is known per se, but in the present use to a certain extent and certain position to the line grid it is new.
