Abstract
(DE)
Während je zwei einander zugeordnete Lichtwellenleiterenden (LW11, LW21) mit Hilfe mindestens einer Positioniereinrichtung (PO2) unter Vorgabe eines axialen Soll-Verfahrwegs (SW) relativ zueinander verschoben werden, wird Messlicht (ML) über deren Längsspalt (SP) übergekoppelt. Die örtliche Intensitätsverteilung (IV) von Interferenzen dieses Messlichts im Längsspalt (SP) wird erfasst, daraus der von der Positioniereinrichtung (PO2) tatsächlich bewirkte Ist-Verfahrweg (IW) ermittelt und dieser dem Soll-Verfahrweg (SW) zur Kalibrierung des axialen Verfahrwegs der Positioniereinrichtung (PO2) zugeordnet.
(EN)
While two mutually allocated optical waveguide ends (LW11, LW12) are moved in relation to each other with the aid of at least one positioning device (PO2) by specifying a set axial traverse path (SW), a measuring light (ML) is overcoupled through their longitudinal gap (SP). Local intensity distribution (IV) of interferences of said measuring light in the longitudinal gap (SP) is detected, the real traverse path (IW) actually covered by the positioning device (PO2) is determined and allocated to the set traverse path (SW) for calibrating the axial traverse path of the positioning device (PO2).
(FR)
Pendant que deux extrémités de guides d'ondes optiques (LW11, LW21) associées entre elles sont déplacées l'une par rapport à l'autre, au moyen d'au moins un dispositif de positionnement (PO2), dans l'hypothèse d'un trajet axial théorique (SW), une lumière de mesure (ML) est couplée par superposition via une fente (SP). La répartition d'intensité locale (IV) des interférences de cette lumière de mesure dans la fente (SP) est détectée, ce qui permet de déterminer le trajet réel (IW) provoqué effectivement par le dispositif de positionnement (PO2), ce trajet étant ensuite associé au trajet théorique (SW) pour l'étalonnage du trajet axial du dispositif de positionnement (PO2).
