Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen eines Grundkörpers für einen Laserkreisel, wobei der Grundkörper mit Kanälen versehen wird, die einen polygonalen optischen Weg bilden.The present invention relates to a method for producing a Base body for a laser gyroscope, the base body with channels is provided, which form a polygonal optical path.
Aus der DE 29 39 946 und der DE 32 17 695 sind Laserkreisel der eingangs genannten Art bekannt. Solche Laserkreisel dienen dazu, Drehbewegungen bzw. Winkelgeschwindigkeiten z. B. von Flugkörpern zu ermitteln. Die Funktion eines Laserkreisels basiert darauf, daß monochromatische Lichtbündel einen geschlossenen optischen Weg in entgegengesetzte Richtungen durchlaufen. Wird nun der Laserkreisel in eine Drehbewegung versetzt, so ändern sich die Umlaufgeschwindigkeiten und damit die Frequenzen der beiden gegenläufigen Lichtbündel konträr zueinander. Die Übertragung beider Lichtbündel ergibt ein Interferenzspektrum, aus dem die Drehgeschwindigkeit herleitbar ist. Der optische Weg besteht gemäß dem Stand der Technik aus mehreren ein Poly gon (z.B. Dreieck) bildenden Kanälen, die durch einen beispielsweise aus Quarzglas hergestellten Grundkörper verlaufen. An den Polygonecken sind Spiegel angeordnet, welche die Lichtstrahlen von einem Kanal in einen ande ren umleiten.From DE 29 39 946 and DE 32 17 695 are laser gyros at the beginning known type known. Such laser gyros are used to prevent rotary movements or Angular velocities z. B. to determine missiles. The function of a laser gyroscope is based on the fact that monochromatic light beams unite one traverse the closed optical path in opposite directions. If the laser gyroscope is now set into a rotary motion, the change Orbital speeds and thus the frequencies of the two opposing ones Beams of light contrary to each other. The transmission of both light beams results an interference spectrum from which the rotational speed can be derived. According to the prior art, the optical path consists of several poly gon (e.g. triangle) forming channels that are characterized by an example Base body made of quartz glass run. At the polygon corners are Mirrors arranged, which the light rays from one channel to another redirect.
Das erfindungsgemäße Verfahren mit den Merkmalen des Anspruches 1 hat den Vorteil, daß es die Herstellung des Grundkörpers eines Laserkreisels mit geringem Aufwand ermöglicht. Das gilt vor allem, wenn die zwei Teilkörper, aus denen der Grundkörper zusammengesetzt wird, gießtechnisch hergestellt werden. Hiermit lassen sich die den optischen Weg im Grundkörper bildenden Kanäle mit sehr hoher Genauigkeit realisieren.The inventive method with the features of claim 1 has the Advantage that it has the manufacture of the base body of a laser gyroscope enables little effort. This is especially true if the two partial bodies, from which the base body is assembled, manufactured by casting will. This enables the optical path in the base body to be formed Realize channels with very high accuracy.
Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels wird nun die Erfindung näher erläutert.Based on an embodiment shown in the drawing the invention explained in more detail.
Die Figur zeigt in perspektivischer Darstellung zwei Teilkörper 1 und 2, die nach ihrer Herstellung zu einem Grundkörper für einen Laserkreisel zusammengefügt werden. Die Teilkörper 1 und 2 werden zweckmäßigerweise aus einem schmelzbaren Werkstoff (z.B. Quarzglas) in einer Form gegossen. Da beide Teilkörper 1 und 2 identisch sind, reicht für ihren Guß eine einzige Form aus. Jeder der Teilkörper 1 und 2 weist, wie der Figur am Beispiel des Teilkörpers 1 zu entnehmen ist, eine Trennfläche (punktierte Fläche) 3 auf. Mit diesen Trennflächen 3 werden die fertiggestellten Teilkörper 1, 2 mit einander verbunden (z. B. durch Glaslot). In der Trennfläche 3 sind drei ein Dreieck umschließende, entlang ihrer Längsachse geteilte Kanäle 4, 5 und 6 angeformt.The figure shows a perspective view of two partial bodies 1 and 2 , which after their manufacture are joined together to form a base body for a laser gyroscope. The sub-bodies 1 and 2 are expediently cast in a mold from a fusible material (eg quartz glass). Since both partial bodies 1 and 2 are identical, a single shape is sufficient for their casting. Each of the partial bodies 1 and 2 , as can be seen in the figure using the example of the partial body 1 , has a separating surface (dotted surface) 3 . The finished partial bodies 1 , 2 are connected to one another with these separating surfaces 3 (for example by glass solder). In the separating surface 3 , three channels 4 , 5 and 6 are formed which surround a triangle and are divided along their longitudinal axis.
Die in jedem Teilkörper 1, 2 eingelassenen halbierten Kanäle 4, 5, 6 ergän zen sich bei der Verbindung der Teilkörper zu vollständigen Kanälen.The halved channels 4 , 5 , 6 embedded in each partial body 1 , 2 complement each other when connecting the partial bodies to complete channels.
Es ist zweckmäßig bei der Herstellung der beiden Teilkörper 1 und 2 an den Ecken der ein Polygon (hier Dreieck) bildenden Kanäle 4, 5, 6 Aufnahmen 7, 8, 9 für Umlenkspiegel mit anzuformen.It is useful in the manufacture of the two partial bodies 1 and 2 at the corners of the channels 4 , 5 , 6 receptacles 7 , 8 , 9 forming a polygon (here triangle) for deflecting mirrors.
