Description

Fernsehkamera mit mehreren Bildfängerröhren Die Erfindung betrifft eine Fernsehkamera mit mehreren Bildfängerröhren, z. B. Vidiconröhren, vorzugsweise Farbfernsehkamera.TV Camera With Multiple Image Capture Tubes This invention relates to a television camera with multiple image capture tubes, e.g. B. Vidicon tubes, preferably Color television camera.

Der Erfindung liegt die Aufgabe zugrunde, mehrere Bildfängerröhren mit den dazugehörigen Ablenk-und Fokussierspulen möglichst raumsparend in einem kleinen Gehäuse unterzubringen.The invention is based on the object of providing a plurality of image capture tubes with the associated deflection and focusing coils in one as space-saving as possible to accommodate small housing.

Zur Lösung dieser Aufgabe wird gemäß der Erfindung vorgeschlagen, daß die Bildfängerröhren innerhalb einer gemeinsamen Fokussierspule angeordnet sind. Diese Anordnung hat gegenüber getrennten Fokussierspulen den Vorteil, daß neben einer Einsparung an Bauvolumen die gegenseitige Beeinflussung der Fokussierfelder entfällt. Ferner bringt eine gemeinsame Fokussierspule infolge ihres möglichen günstigen Verhältnisses von Länge zu Durchmesser, wie Versuche ergaben, einen sehr homogenen Feldverlauf innerhalb der Bildfängerröhren mit sich, was eine gute Bildgeometrie gewährleistet.To solve this problem it is proposed according to the invention, that the image capture tubes are arranged within a common focusing coil. This arrangement has the advantage over separate focusing coils that in addition to a saving in construction volume the mutual influence of the focusing fields not applicable. Furthermore, a common focus coil is beneficial because of its potential The ratio of length to diameter, as tests have shown, is very homogeneous Field course within the image capture tubes with what a good image geometry guaranteed.

Gemäß einer Ausführungsform der Erfindung kann hierzu die Anordnung derart getroffen werden, daß mindestens zwei der Bildfängerröhren derart angeordnet sind, daß ihre Signalplatten in gleicher Ebene liegen.According to one embodiment of the invention, the arrangement be taken such that at least two of the image capture tubes are arranged in such a way are that their signal plates are in the same plane.

Die Erfindung ist nachstehend an Hand der Zeichnungen erläutert, welche die achsenparallele Anordnung von drei Vidiconröhren V1, V2 und V3 innerhalb einer diese umschließenden gemeinsamen Fokussierspule F zeigen. Jeder der Vidiconröhren V1, V2, V3 ist ein Ablenksystem Al, A2, As zugeordnet, welches von einer zylinderförmigen Abschirmung ZA1, ZA2, ZA3 umgeben ist. In F i g. 1 ist ein Ausführungsbeispiel gezeigt, bei welchem die Signalplatten S1, S2, S3 in einer Ebene angeordnet sind: In dem in F i g. 2 dargestellten Ausführungsbeispiel sind nur die Signalplatten S1 und S2 der Vidiconröhren V1 und V2 in einer Ebene angeordnet, während die Vidiconröhre V3 aus optischen Gründen zurückgesetzt ist, so daß ihre Signalplatte S3 nicht mehr in der Ebene der Signalplatten S1 und S2 liegt. Die Abschirmzylinder ZA1, ZA2 und ZA3 können bis über die Ebene der Signalplatte der zugehörigen Vidiconröhre vorgezogen sein. Auch ist es zweckmäßig, der Fokussierspule F eine so große Länge zu geben, daß diese über die Signalplatten S1, S2, S3 der Vidiconröhren V1, V2, V3 übersteht. Die Abschirmzylinder ZA1, ZA2, ZA3 bestehen zweckmäßig aus nichtmagnetischem elektrisch leitendem Werkstoff.The invention is explained below with reference to the drawings, which show the axially parallel arrangement of three vidicon tubes V1, V2 and V3 within a common focusing coil F surrounding them. Each of the vidicon tubes V1, V2, V3 is assigned a deflection system A1, A2, As , which is surrounded by a cylindrical shield ZA1, ZA2, ZA3. In Fig. 1 shows an embodiment in which the signal plates S1, S2, S3 are arranged in one plane: In the one shown in FIG. 2, only the signal plates S1 and S2 of the vidicon tubes V1 and V2 are arranged in one plane, while the vidicon tube V3 is set back for optical reasons, so that its signal plate S3 is no longer in the plane of the signal plates S1 and S2. The shielding cylinders ZA1, ZA2 and ZA3 can be pulled up over the level of the signal plate of the associated vidicon tube. It is also expedient to give the focusing coil F a length so great that it protrudes beyond the signal plates S1, S2, S3 of the vidicon tubes V1, V2, V3. The shielding cylinders ZA1, ZA2, ZA3 are expediently made of non-magnetic, electrically conductive material.

In manchen Fällen, z. B. bei der in F i g. 2 gezeigten Anordnung, ist es von Vorteil, besondere Vorrichtungen zur Beeinflussung des Feldes der Fokussierspule F vorzusehen, die eine Ver- oder Entzerrung ihres Feldes bewirken. Hierzu können zusätzlich einstellbare, den einzelnen Systemen zugeordnete Spulen oder Magnete verwendet werden, die beispielsweise gleiche Feldverhältnisse herstellen, wenn die Signalplatten der Vidiconröhren nicht in einer gemeinsamen Ebene angeordnet sind.In some cases, e.g. B. at the in F i g. 2 arrangement shown, it is advantageous to use special devices for influencing the field of the focusing coil F to be provided, which cause a distortion or equalization of their field. You can do this Additionally adjustable coils or magnets assigned to the individual systems are used, for example, produce the same field conditions when the Signal plates of the vidicon tubes are not arranged in a common plane.
