Paper Abstract

Some years ago Lawrence and Moore developed the basic principles of integrating geometrical and physical optics by incorporating conventional ray-based methods into the diffraction-based program GLAD. This paper discusses more specifically the difficulties in ray-based methods and hybrid methods in which physical optics is encapsulated within a ray-based program. Phase singularities are common in physical optics analysis and are shown to pose severe difficulties for ray-based methods. Time-averaged, through- focus behavior of a clipped excimer beam is taken as an illustration of a problem which can not be solved by ray- based methods but is readily solved with the lensgroup operator method of Lawrence and Moore. Beam reshaping is taken as a second example where diffractive effects should be considered.
