Abstract
Foreliggende oppfinnelse er relatert til en fremgangsmåte og en optisk fibermåleinnretning som inkluderer en lyskilde med en lyseffekt P, et Sagnacringinterferometer i hvilket det utbrer seg to motsatt utbredte bølger, en detektor som tar imot en lysfluks fra interferometeret og som konverterer den til et elektrisk signal som representerer den totale faseforskjellen dft mellom de motsatt utbredte bølgene. Den innbefatter også en elektronisk innretning som tar imot det elektriske signalet fra detektoren og som gir et første signal S1 som funksjon av den målte parameteren. Den elektroniske innretningen innbefatter en demodulator som bidrar til å gi det første signalet som funksjon av den målte parameteren og gir et andre signal S2 som funksjon av effekten P til lysfluksen målt av detektoren. I henhold til foreliggende oppfinnelse vil den optiske fasemodulatoren generere en forstyrrelseskomponent dfcp som legger seg til faseforskjellen dfm = dfb + dfcr .
