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.Measurement of integrated densities for grayscale or color composition at irregularly shaped areas on a specimen (52) is performed using a video camera (54) to produce an analog diode noise signal representing the optical power of light associated with the specimen. A modified inexpensive high speed value generator (58) converts the value data into a digital format as an Interactive Data Program (64) transformed into digital optical density values used to determine the net Integrated Density for each irregular shaped area of the sample.
