Paper Abstract

The measurement of the Wiener spectrum associated with screen-film noise has beep widely reported in recent years, and digital data obtained by microdensitometer slit-scanning is now almost a standard art. However, physical autocorrelation techniques, described and developed for other types of imagery, might have powerful advantages in some respects. An analysis is carried out of the fundamental statistics associated with the two approaches, and some attractive features associated with physical autocorrelation are illustrated.
