Abstract

I et interferometrisk avfølingsapparat er en omkaster (24) plassert foran en polarisator (30) som etterfølges av en detektor (34). På denne måte blir de to stråler (22), selv om de forblir innbyrdes ortogonale, rotert kontinuerlig i forhold til polarisatoren. I noen stillinger passerer begge stråler (28) gjennom polarisatoren og blandes, hvorved polarisasjonsfading elimineres. Signalet amplitudemoduleres med omkasterens rotasjonsfrekvens, men denne modulasjon blir fjernet gjennom lavpassfiltrering.
