Description

  

   <Desc/Clms Page number 1> 
 



    Die Erfindung bezieht sich auf einen Lichtstrahlenoszillographen mit einem zwei oder mehrere Pollöcher    aufweisenden Magnetblock und mit zumindest einem in ein Polloch eingesetzten Galvanometer sowie mit einem optischen System zum Abbilden einer mittels des Galvanometerspiegels auslenkbaren Lichtmarke auf einem Aufzeichnungsträger oder einen Bildschirm. 



   Derartige Lichtstrahloszillographen sind bekannt und beispielsweise in dem   Buch"Lichtstrahlenoszillo-     graphiell von W. Härtel u. a.   (Verlag R. Oldenburg, München 1961, insbesondere   S. l19f.) ausführlich be-   handelt. 



   Weiters sind Lichtstrabloszillographen bekannt, mit denen einzelne Grössen sowie auch deren Summe dargestellt bzw. aufgezeichnet werden können (USA-Patentschrift Nr. 2, 167, 124), wobei im zweiten Fall die Grössen   mit Hilfe vonMesswertumformern   in elektrische Signale umgewandelt, diese addiert und das Summensignal dem Galvanometer zugeführt werden. 



   In der USA-Patentschrift Nr. 2,267,   356   ist eine Einrichtung zur gleichzeitigen Aufzeichnung mehrerer Signale mittels Galvanometern beschrieben, wobei diese eine bestimmte Orientierung im Magnetblock aufweisen, so dass der vom Spiegel eines der Galvanometer reflektierte Lichtstrahl auf den Spiegel eines zweiten Galvanometers fällt ; auf diese Weise lässt sich die Summe zweier den Galvanometern zugeführter Grössen darstellen.

Fig. 3 zeigt den Aufbau eines zum Multiplizieren eingerichteten Lichtstrahloszillographen. Zwei miteinander zu multiplizierende elektrische Signale x und y, welche z. B. zwei Ströme J1 und J2 proportional sind, werden an die   Anschlussklemmen --14   und 16-- des des Wandlers --9-- angelegt.

   Infolge des durch die   Schwingspule-13-- fliessenden   Stromes   J 1 wird   diese um den Winkel   CI !   verdreht. Da der Hallgenerator - mitverdreht wird, gilt für die magnetische Induktion : 
B = Bo sin   CI !

    The invention relates to a light beam oscilloscope with a magnet block having two or more pole holes and with at least one galvanometer inserted in a pole hole and with an optical system for imaging a light mark deflectable by means of the galvanometer mirror on a recording medium or a screen.



   Such light beam oscillographs are known and are dealt with in detail, for example, in the book "Lichtstrahloszillographiell" by W. Härtel et al. (Verlag R. Oldenburg, Munich 1961, in particular pp. 19f.).



   Furthermore, light beam oscillographs are known with which individual quantities as well as their sum can be displayed or recorded (USA Patent No. 2, 167, 124), in the second case the quantities are converted into electrical signals with the help of transducers, these are added and that Sum signal are fed to the galvanometer.



   US Pat. No. 2,267,356 describes a device for the simultaneous recording of several signals by means of galvanometers, these having a specific orientation in the magnetic block so that the light beam reflected from the mirror of one of the galvanometers falls on the mirror of a second galvanometer; In this way, the sum of two quantities fed to the galvanometers can be represented.

3 shows the structure of a light beam oscilloscope set up for multiplication. Two electrical signals x and y to be multiplied, which z. B. two currents J1 and J2 are proportional, are applied to terminals --14 and 16-- of the converter --9--.

   As a result of the current J 1 flowing through the voice coil-13--, it is increased by the angle CI! twisted. Since the Hall generator is rotated, the following applies to magnetic induction:
B = Bo sin CI!
