Abstract

Måling av integrerte denslteter for gråskala eller fargesammensetning ved uregelmessig formede områder på et prøvestykke (52) foregår ved bruk av et videokamera (54) for å frembringe et analogt vldeoblldeslgnal som representerer den optiske styrke på lys knyttet til prøvestykket. En modifisert billig høyhastlghets vldeodlgltallserer (58) omformer vldeblldeslgnalet til et digitalt format som et Interaktivt dataprogram (64) omformet til digitale optiske densltetsverdler som benyttes til å bestemme netto Integrert densitet for hvert uregelmessig formet område på prøvestykket.
