Die bekannten Vorrichtungen zum unmittelbaren Anzeigen und Messen elektromagnetischer Schwingungen, bei denen die Eigenschwingung des Meßkreises kontinuierlich und periodisch verändert wird, wobei zum Anzeigen des Augenblicks der Resonanz ein rotierender Resonanzanzeiger dient, sind nicht empfindlich genug, um eine Fern Wellenmessung und eine genaue Darstellung der Dämpfungskurve zu gestatten. Gemäß vorliegender Erfindung, welche die Anwendung eines feststehenden Instrumentes von beliebiger Empfindlichkeit gestattet, wird entsprechend der Veränderung der Eigenschwingung des Empfangsystems der anzeigende Teil eines Indikators bzw. Meßinstrumentes bewegt, wobei durch das Ansprechen des Instrumentes eine Änderung in dieser Bewegung erfolgt.The known devices for the immediate display and measurement of electromagnetic Oscillations in which the natural oscillation of the measuring circuit is changed continuously and periodically, for display purposes At the moment of resonance a rotating resonance indicator is used, are not sensitive enough to make a long-distance wave measurement and to allow an accurate representation of the damping curve. According to the present invention, which involve the use of a fixed instrument of any sensitivity is allowed according to the change in the natural oscillation of the receiving system the indicating part of an indicator or measuring instrument moves, with the response of the instrument a Change in this movement takes place.
Zur Ausführung des Verfahrens kann eineTo carry out the method, a
so Vorrichtung dienen, bei welcher das Schattenbild der von der Lichtquelle α beleuchteten Saite b eines Saitengalvanometers durch den Spalt c hindurch auf den Spiegel d geworfen und von diesem nach der Linie e auf die Skala f reflektiert wird. Der Spiegel ist auf der Achse g der Drehplatten h eines rotierenden Kondensators befestigt, durch den die Eigenschwingung des Meßsystems periodisch verändert wird. Beim Rotieren des Kondensators beschreibt das punktförmige Bild der Saite auf der Skala einen Kreis i. Beim Ansprechen des Instrumentes wird das Bild der Saite aus seiner Bahn abgelenkt in der Weise, daß der Punkt immer an der Stelle seiner Bahn, die der Resonanz mit der jeweilig erregenden Schwingung entspricht, eine Resonanzkurve k, I beschreibt. Wird die Skala entsprechend geeicht, so kann man an diesen Stellen die Wellenlänge unmittelbar ablesen.Thus, the device is used in which the shadow image of the string b of a string galvanometer illuminated by the light source α is thrown through the gap c onto the mirror d and is reflected by this along the line e onto the scale f. The mirror is attached to the axis g of the rotating plates h of a rotating capacitor, by means of which the natural oscillation of the measuring system is periodically changed. When the capacitor rotates, the punctiform image of the string on the scale describes a circle i. When the instrument responds, the image of the string is deflected from its path in such a way that the point always describes a resonance curve k, I at the point on its path that corresponds to the resonance with the respective exciting oscillation. If the scale is calibrated accordingly, the wavelength can be read off directly at these points.
Natürlich kann man den Spiegel so klein wählen bzw. so anordnen, daß der Lichtzeiger nur im Augenblick des Ansprechens auf ihn fällt. Statt der geeichten Skala kann auch eine Signalscheibe verwendet werden, wenn man die Vorrichtung zur Übertragung von Kommandos benutzen will, wobei jedem Kommando eine besondere Schwingungszahl zugeordnet ist.Of course you can choose the mirror so small or arrange it so that the light pointer falls only at the moment of addressing him. Instead of the calibrated scale, you can also use A signal disc can be used when using the device to transmit Wants to use commands, with each command assigned a special number of vibrations is.
Soll der anzeigende Teil zum Auslösen irgendeiner Bewegung oder z. B. zum Stillsetzen eines entsprechend der Veränderung der Eigenschwingung des Empfangssystems bewegten Organs dienen, so kann dies entweder unmittelbar geschehen oder mittelbar dadurch, daß durch den anzeigenden Teil ein Lokalstromkreis geschlossen wird. Bei einem Instrument mit Lichtzeiger werden zu diesem Zweck in an sich bekannter Weise Lichtrelais (Selenzellen) angewendet.Should the indicating part be used to initiate any movement or e.g. B. to shutdown one moved according to the change in the natural oscillation of the receiving system Serve organ, this can happen either directly or indirectly by the fact that a local circuit is closed by the indicating part. With an instrument Light relays (selenium cells) are used for this purpose in a known manner. applied.
