Abstract

En anordning (10) eller fremgangsmåte bestemmer gapet (11) mellom en montasje (12) av et ror (13) og en sylindrisk flottør (14) beliggende hovedsakelig konsentrisk l roret (13). Bi elliptisk polarisert lysstråle (A) med bølgelengde for hvilke materialene l roret (13) og gapet (11) er transparente eller gjennomskinnelige, går langs en optisk akse (C). Brytningslndeksen for roret (13) og flottøren (14) er større enn brytnlngsIndeksen for materialet l gapet. Innretninger translaterer og roterer montasjen (12) langs og om sin lengdeakse. (F) sora frembringer en belysning (B). En lysfiltrerende innretning (21) langs den optiske akse (C) bak montasjen (12) sperrer lys fra belysningen (B) reflektert av montasjen (12) og brutt av røret (13), gapet (11) mellom røret og flottøren (14) og flottøren, og transmitterer lys fra belysningen brutt av roret og gapet mellom roret og flottøren. Lysdetekterende innretninger (15) mottar transmittert lys og gir signaler til en slgnalbehandlende innretning (16). Fremgangsmåten innbefatter å transmittere den monokromatlske stråle med elliptisk, polarisert lys langs den optiske akse (C) til montasjen (12), fokusering av lysstrålen (A), translatere og rotere montasjen gjennom lyset, som frembringer en belysning (B), filtrere belysningen (B) ved å sperre belysningen reflektert av montasjen (12) og brutt av flottøren, roret og gapet mellom roret og flottøren, og transmittere belysningen brutt av røret og gapet mellom roret og flottøren.
