Paper Abstract

Image evaluation and image mensuration are usually assumed to be problems to which a linear system's analysis is applicable. Hence, the aids used in viewing and studying the image, e.g. , viewers, tube magnifiers, microscopes, microdensitometers, etc. , are assumed to use incoherent illumination of the object resulting in a system which is linear in intensity. Departures from this ideal situation occur at moderate line frequencies in the object and the effects of illuminating the object with partially coherent light are of interest. Some examples of these effects are discussed with particular reference to evaluation and measurement of object information.
