Abstract: An electrooptical scanning system's resolution capability can be described by a modulation transfer function similar to the aperture admittance of Mertz and Gray. Image formation, image dissection and facsimile synthesis can be treated as operations in which each subsystem's input is averaged over a finite interval. The modulation transfer function thus derived places in perspective the effects that the optics, image dissector, video electronics and display have on the quality of the final image facsimile. As an illustrative supplement, the averaging-aperture analogy can be the basis for a simple computer program to produce simulated image-facsimile intensity cross sections from inputs simulating resolution-target stripes and other test patterns.
