Abstract
Den foreliggende oppfinnelse tilveiebringer et optisk system som er virksomt for å eliminere parallakseforvrengning i et oppfanget bilde. Særlig eliminerer anordningen parallakseforvrengning i et håndflateavtrykksbilde. Anordningen innbefatter et prisme som har en mottagende overflate og en objektoverflate. En håndflate anbringes på den mottagende overflaten og et lys belyser den monagende overflaten slik at et bilde som er representativt for håndflaten forplantes fra objektoverflaten. Det forplantede bildet irmbefatter et flertall av segmenter. En linse forstørrer selektivt hvert av segmentene med en forskjellig størrelse for å skape et flertall av forstørrede segmenter som har lik lengde. Et bilderegistrerende medium oppfanger så de forstørrede segmenter. Oppfinnelsen Ulveiebringer også en sylindrisk anordning som er betjenbar for å oppfange bildet av håndflaten, der håndflaten kan rulles over en gjennomsiktig sylinder og reflektert lys oppfanges av et registreringsmedium som er representativt for håndflateavtrykket.
