Abstract

Et optlsk-fiberinterferrometrlsk system (10) Innbe- fatter et par enkelt-modus, polarlsasjons-bevarende fibre (24, 26) som har fjerntliggende og nærliggende ender. Kledningen (46) av en valgt del (50) av et av fibrene er blitt fjernet for å tillate et gradvis avtagende parti av en lysbølge som beveger seg innenfor fiberet å samvirke med et eventuelt medium som omgir den valgte delen av fiberet. En lyskilde (12) for frembringelse av et lys av kjent karakter er koplet (20) til de nærliggende ender av paret av optiske fibre for å Innføre et klldesignal til paret av fibre. En reflektor (98) ved de fjerntliggende ender av de optiske fibrene reflekterer lyset fra de fjerntliggende ender tilbake til lyskilden. Retursignalene anvendes til å konstruere et interferrogram som observeres for å detektere eventuell modulasjon l fasen for lyssignale- ne. Modulasjonen granskes forholdsmetrislt for å utlede en endring i brytningsindeksen for det medium som omgir den valgte delen og l alt vesentlig fritt for eventuell milJømessig-indusert fasestøy.
