Abstract

A technique is proposed for generalized spatial filtering with large, incoherent light sources, making use of the photographic Herschel effect. Outputs are obtained by a single exposure in a conventional optical printer; no scanning equipment, photographic masks or special developing processes are used. Exploratory experiments with this technique are reported and desirable improvements are pointed out. Several different kinds of image processing for various applications are demonstrated.
