Abstract
Description
Vorrichtung zur Durchleuchtung und Abbildung einesDevice for fluoroscopy and imaging of a
langgestreckten Gebildes Die Erfindung betrifft eine Vorrichtung zur Durchleuchtung und Abbildung eines langgestreckten Gebildes mit einem Kern und einer den Kern umgebenden Umhüllung, insbesondere zur Überwachung der Lage eines elektrischen oder optischen Leiters in einer Umhüllung und zur Messung des Außendurchmessers des umhüllten Leiters, mit zwei senkrecht zueinander angeordneten Strahlungsquellen, deren Strahlengänge sich in der Bahn des langgestreckten Gebildes kreuzen, das langgestreckte Gebilde durchleuchten und auf einem Schirm abbilden.elongated structure The invention relates to a device for X-raying and imaging of an elongated structure with a core and a the sheath surrounding the core, in particular for monitoring the position of an electrical or optical conductor in a sheath and for measuring the outside diameter of the sheathed conductor, with two radiation sources arranged perpendicular to one another, whose beam paths cross in the path of the elongated structure, the elongated one Shine through structures and display them on a screen.
Eine derartige Vorrichtung ist aus der DE-OS 24 02 480 bekannt, die eine Anordnung zur selbständigen Zentrierung eines elektrischen Leiters in einer Isolierhülle beschreibt.Such a device is known from DE-OS 24 02 480 which an arrangement for the independent centering of an electrical conductor in a Insulation describes.
Die Lage des Leiters wird dabei mittels die Isolierhülle durchdringender Strahlen aus zwei senkrecht zueinander stehenden Strahlungsquellen abgebildet. Bei diesem Verfahren wirken sich die Lichtbrechung und Reflexion an der Oberfläche störend auf die Genauigkeit der MeZergebnisse aus.The position of the conductor becomes more penetrating by means of the insulating sleeve Rays from two mutually perpendicular radiation sources shown. at This process has a disruptive effect on the refraction of light and reflection on the surface on the accuracy of the MeZ results.
Die Brechung des aus der Umhüllung austretenden Lichts kann insbesondere bei exzentrischen Leitern in nicht runden Umhüllungen zu falschen Meßergebnissen führen.The refraction of the light emerging from the envelope can in particular in the case of eccentric conductors in non-round sheaths lead to incorrect measurement results to lead.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art anzugeben, die störende Lichtbrechungen und Reflexionen an der Oberfläche der zu durchleuchtenden Umhüllung ausschließt.The invention is based on the object of providing a device of the initially described Specify the type of disruptive refractions and reflections on the Excludes the surface of the envelope to be transilluminated.
Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß im Schnittpunkt der Strahlengänge der Strahlungsquelle ein Behälter angeordnet ist, welcher eine Flüssigkeit enthält, deren Brechungsindex angenähert gleich dem des Umhüllungsmaterials des langgestreckten Gebildes ist und in der die Durchleuchtung des langgestreckten Gebildes erfolgt. Als Flüssigkeit enthält der Behälter zweckmäßigerweise ein leicht verdampfendes Lösungsmittel mit geeignetem Brechungsindex.This object is achieved according to the invention in that at the point of intersection the beam paths of the radiation source, a container is arranged, which a Contains liquid whose refractive index is approximately equal to that of the cladding material of the elongated structure and in which the transillumination of the elongated Formed takes place. The container expediently contains a light liquid as the liquid evaporating solvent with suitable refractive index.
Die Erfindung bietet den Vorteil, daß die Bestimmung der Lage des Kerns in der Umhüllung und die Messung des Durchmessers des Kerns und der Umhüllung durch die Durchleuchtung im Flüssigkeitsbad einfacher und genauer wird. Bei unrunder Umhüllung brauchen die Meßergebnisse nicht mehr korrigiert zu werden. Auch die Lage durchsichtiger Kerne, wie zum Beispiel optischer Fasern, in ihrer Umhüllung kann leicht bestimmt werden. Es ist mit diesem einfachen Gerät möglich, das umhüllte langgestreckte Gebilde zu durchleuchten und vergröSert abzubilden, wobei auf einfache Weise die Qualität der Umhüllung beurteilt werden kann. So lassen sich Einschlüsse, Fehler usw. in der Umhüllung feststellen.The invention has the advantage that the determination of the location of the Core in the cladding and the measurement of the diameter of the core and cladding becomes easier and more precise through the fluoroscopy in the liquid bath. With out-of-round The measurement results no longer need to be corrected will. Also the position of transparent cores, such as optical fibers, in theirs Serving can be easily determined. With this simple device it is possible to illuminate the enveloped elongated structure and to depict it enlarged, whereby the quality of the casing can be assessed in a simple manner. Let it be Inclusions, defects, etc. are found in the envelope.
Anhand der Zeichnung wird die Erfindung erläutert. Mit 1 ist das langgestreckte Gebilde, im dargestellten Fall ein isolierter Leiter, bezeichnet, der im Schnittpunkt der Strahlengänge 4 und 5 der Lichtquellen 2 und 3 geführt ist.The invention is explained with the aid of the drawing. With 1 it is elongated Structure, in the case shown, an insulated conductor, denotes the point of intersection the beam paths 4 and 5 of the light sources 2 and 3 is guided.
Zur Führung der Strahlengänge 4 und 5 und zur Vergröferung des bei der Durchleuchtung entstehenden Bildes sind die Linsen 7 vorgesehen. Die Abbildung des umhüllten Leiters 1 erfolgt auf einem Schirm 6, zu dem der Strahl 4 von der Lichtquelle 2 mittels eines Spiegels 10 umgelenkt wird.To guide the beam paths 4 and 5 and to enlarge the at The image resulting from the fluoroscopy is provided with the lenses 7. The illustration of the sheathed conductor 1 takes place on a screen 6, to which the beam 4 from the Light source 2 is deflected by means of a mirror 10.
Anstelle eines Schirms kann die Abbildung auch über eine Fernsehkamera auf einem Monitor erfolgen.Instead of a screen, the image can also be shown using a television camera be done on a monitor.
Gemäß der Erfindung ist am Schnittpunkt der Strahlengänge 4 und 5 ein Behälter 8 angeordnet, der eine Flüssigkeit 9 enthält. Die Flüssigkeit 9 hat einen Brechungsindex, der angenähert gleich dem des Umhüllungsmaterials ist. Dadurch werden störende Reflexionen, Brechungen und Beugungserscheinungen an der Oberfläche des umhüllten Leiters weitgehend ausgeschaltet, so daß sehr genaue Messungen möglich sind. Die Auswahl der Flüssigkeiten hängt natürlich von den beteiligten Materialien ab. Für Polyamidumhüllungen kommen als Flüssigkeiten mit geeignetem Brechungsindex zum Beispiel Trichloräthylen, Glycerin, Silikonöl usw. in Frage.According to the invention, the beam paths 4 and 5 are at the intersection a container 8 is arranged which contains a liquid 9. The liquid 9 has an index of refraction approximately equal to that of the cladding material. Through this there are disturbing reflections, refractions and diffraction phenomena on the surface of the sheathed conductor largely switched off, so that very precise measurements are possible are. The choice of liquids depends of course on the materials involved away. Liquids with a suitable refractive index are used for polyamide coatings for example trichlorethylene, glycerine, silicone oil, etc. in question.
