<title>Diffraction Evaluation Of General Optical Systems</title>

Abstract

Techniques for the Fraunhofer diffraction evaluation of general optical systems have been developed and incorporated in the computer program ACCOS V. No restrictions are made with respect to symmetry, allowing any combination of tilted, decentered or deformed elements, arbitrary off -axis field points, and unusual aperture shapes.Systems with nonuniform illuminance over the image space wavefront (in the presence of pupil aberrations or apodization, for example) are correctly treated. Significant features of the methods used and applications to selected optical systems are discussed.
