Abstract

A versatile program has been developed for determining the diffracted intensity distribution far from the image center for a wide variety of obscured apertures. The total obscuration is constructed from "building blocks" consisting of triangles, rectangles, bars, and annular rings. Closed formed solutions of the Fraunhofer diffraction integrals for the building blocks are combined by means of Babinet's principle to obtain the point spread function. An example is given demonstrating the influence of fine mechanical structure in the obscuration on the image structure far from the image center.
