Abstract
Description
Dic zu messende optische Faser 1 ist achsparallel zur Faser 2 auf einem Manipulator 5 befestigt. Ihr Ende 6 ragt über den Rand 7 des Manipulators 5 um einen Wert zx hinaus, welcher mit einer relativ großen Toleranz + t eingehalten werden muß, was für eine Bedienungsper- son mühelos ohne Zuhilfenahme von Vorrichtungen möglich ist. The optical fiber 1 to be measured is axially parallel to the fiber 2 a manipulator 5 attached. Your end 6 protrudes over the edge 7 of the manipulator 5 by a value zx, which is complied with with a relatively large tolerance + t must be what kind of operator lock son effortlessly without assistance of devices is possible.
Dic folgenden Justier- und Einstellvorgängc vcrlaufen automatisch. Der Manipulator 5 erhält Befehle zur Bewegung in den Richtungen x, y und z von einer Steuereinrichtung, welche einerseits feste Bewegungsschritte und andererseits nach einem Soll-lstwert-Vergleich geregelte Bewegungen zum Fixpunkt D hin veranlaßt. The following adjustment and setting processes run automatically. The manipulator 5 receives commands to move in the directions x, y and z from one Control device, which on the one hand fixed movement steps and on the other hand after a setpoint / actual value comparison causes controlled movements to the fixed point D.
Vor dem Auflegen der Faser 1 auf den Manipulator 5 wird dieser in eine vorbestimmte Abstandslage gefahren, deren Koordinaten derart in die Steuereinrichtung einprogrammiert sind, daß der Abstand der Faserenden iny-Richtung minimal ist. Before the fiber 1 is placed on the manipulator 5, it is in a predetermined distance driven, the coordinates of which in the control device are programmed that the distance between the fiber ends in the y-direction is minimal.
Nach dem Auflegen der Faser 1 wird der automatische Kopplungsablauf veranlaßt. Die Faser 1 ist derart auf dem Manipulator 5 aufgelegt, daß sie einerseits um die Länge zl +t übersteht und andererseits in x-Richtung einen geringen Abstand xo vom Fixpunkt D hat. After the fiber 1 has been placed, the automatic coupling process starts caused. The fiber 1 is placed on the manipulator 5 in such a way that on the one hand it protrudes by the length zl + t and on the other hand a small distance in the x-direction xo from the fixed point D.
Nunmehr bewegt sich der Manipulator 5 in z-Richtung um einen festen Schritt zum Fixpunkt D hin, welche um den kleinen Wert zo größer als die Differenz (a + tz,) ist. Danach bewegt sich der Manipulator 5 in x-Richtung zum Fixpunkt D hin. Beim Erreichen des Fixpunktes D kann der von der Sendefaser 8 durch den Fixpunkt D in y-Richtung gesendete Lichtstrahl nicht mehr den optischen Empfänger 9 erreichen. Durch Differenzierung der Intensität des vom optischen Empfänger gemessenen Lichteinfalls enthält man eine Information über das Minimum des Lichteinfalls. Bei diesem Minimum, welches man erhält, wenn die Faser 1 genau durch den Fixpunkt D verläuft, veranlaßt die Steuereinrichtung, daß die Bewegung des Manipulators 5 angehalten wird.The manipulator 5 now moves around a fixed one in the z-direction Step towards the fixed point D, which is greater than the difference by the small value zo (a + tz,) is. The manipulator 5 then moves in the x direction to the fixed point D there. When the fixed point D is reached, the transmission fiber 8 can pass through the fixed point D light beam sent in the y direction no longer reach the optical receiver 9. By differentiating the intensity of the incident light measured by the optical receiver contains information about the minimum incidence of light. At this minimum which is obtained when the fiber 1 runs exactly through the fixed point D caused the control device that the movement of the manipulator 5 is stopped.
Nachdem nunmehr die Faser 1 in x-Richtung den Fixpunkt erreicht hat, wird der Manipulator 5 solange in z-Richtung zum Fixpunkt D hin bewegt, bis der optische Empfänger 9 einen erhöhten Lichteinfall mißt. In diesem Augenblick wird der Manipulator 5 angehalten, da der Endpunkt 6 der Faser 1 auch in z-Richtung den Fixpunkt D erreicht hat. Nunmehr ist der lustiervorgang beendet Abschließend wird der Manipulator 5 von der Steuereinrichtung zu einem festen Bewegungsschritt in Richtung x auf das Ende 4 der Faser 2 hin veranlaßt, welcher genau die Länge des bekannten Abstandes des Fixpunkt D vom Ende 4 der Faser 2 beträgt. Bei nicht zu hohen Genauigkeitsanforderungen ist der Kopplungsvorgang damit abgeschlossen. Now that the fiber 1 has reached the fixed point in the x-direction, the manipulator 5 is moved in the z-direction towards the fixed point D until the optical receiver 9 measures an increased incidence of light. At this moment it will the manipulator 5 stopped because the end point 6 of the fiber 1 is also in the z-direction Has reached fixed point D. The lustier process is now ended the manipulator 5 from the control device to a fixed movement step in Direction x causes the end 4 of the fiber 2, which is exactly the length of the known distance of the fixed point D from the end 4 of the fiber 2 is. When not to The coupling process is thus completed with high accuracy requirements.
Insbesondere bei der Kopplung von optischen Fasern ist es vorteilhaft, eine Feinjustierung der Koaxialität der Fasern folgen zu lassen. Das geschieht vorteilhaft mit Hilfe eines durch die Faser 2 gesendeten Lichtstrahls, welcher in die Faser 1 geleitet und an deren anderen Ende gemessen wird. Der vorangegangene Justiervorgang ist auf jeden Fall so genau, daß die Enden der Fasern 1 und 2 mit Sicherheit in der Weise einander gegenüber stehen, daß zumindest ein erheblicher Teil des von der Faser 2 gesendeten Lichtstrahls in die Faser 1 eintritt. Der Manipulator wird in diesem Bereich zu verlangsamten Regelbewegungen veranlaßt und in eine Stellung gefahren, wo die maximale Lichtmenge am Ausgang der Faser 1 gemessen wird. Particularly when coupling optical fibers, it is advantageous to to allow fine adjustment of the coaxiality of the fibers to follow. This is done advantageously with the aid of a light beam transmitted through the fiber 2 which enters the fiber 1 and measured at the other end. The previous adjustment process is in any case so precise that the ends of fibers 1 and 2 are definitely in face each other in such a way that at least a substantial part of the The light beam transmitted from the fiber 2 enters the fiber 1. The manipulator will in this area caused to slow down regular movements and into a position driven, where the maximum amount of light is measured at the output of fiber 1.
Nachdem nunmehr der Kopplungsvorgang abgeschlossen ist, können Messungen durchgeführt oder die Faserenden miteinander fest verbunden werden, beispielsweise durch Verschweißen. Now that the coupling process has been completed, measurements can be made performed or the fiber ends are firmly connected to one another, for example by welding.
