Abstract

I overensstemmelse med frem- gangsmåten ifølge oppfinnelsen forbedres optisk inspeksjon av en gjennomskinnelig artikkel (3), særlig optisk inspeksjon av en konkav bunn av en beholder, ved hvilken artikkelen (3) anbringes mellom en strålingskilde (1) og et bilde- registreringsapparat (2) og et bilde av artikkelen registreres og behandles, ved at i det minste ett optisk korreksjons- element (7.1) anbringes i banene til stråler mellom strålingskilden (l) og bilderegistreringsapparatet (2) for å korrigere strålebaner som forårsaker uønskede, mørke eller svarte steder på bildet, slik at slike mørke eller svarte steder hindres eller gjøres lysere, slik at det frembringes et fyllestgjørende bilde for tilfredsstillende bilde- analyse.
