Abstract

Måling av integrerte tettheter til uregelmessig formede områder av en preve blir utført ved bruk av et videokamera for å avlede et analogt vldeoblldeslgnal soæ er representativt for den optiske Intensiteten til lys tilknyttet preven. En modifisert lavkostnads, høyhastlghets vldeodlgltalIserer omformer vldeobllde- slgnalet til et digitalt format som et Interaktivt datamasklnprogram omformer til digitale optiske tetthetsverdler som blir brukt til å bestemme netto Integrert tetthet av hvert uregelmessig formet område på preven.
