Paper Abstract

In 1963 Gordon Rogers published a paper in which he described the formation of optical images in terms of transformations of the coherence function associated with the wave propagating from the object, passing through lenses, and continuing on to the image plane. Of particular importance, he noted (a) that a clear aperture can be treated as the superposition of a large number o pinholes, the pinhole density being so high that they effectively fill the aperture, and (b) that each pair of pinholes produces in the image pl ane a sinusoidal fringe pattern. The superposition of the many fringe patterns then determines the image intensity distribution. In this paper Rogers' concept is extended to include the formation of images of 3D full-color objects and the formation of images in a particular super-resolving imaging system.
