Paper Abstract

Third generation synchrotron light sources present new challenges to x-ray optics calculations. Due to the high brilliance (thus small dimensions) of the source and the long optical paths, the transverse coherence lengths are quite nonnegligible, often of order of hundreds of microns. In such situation beam propagation calculations based on purely geometrical optics may yield large errors and a more complete wave treatment is needed. This is especially true for beam defining apertures. The purpose of this paper is to present a calculational approach which, utilizing a 'variance matrix' representation of the beam allows to evaluate the wave propagation along an optical system and through arbitrary apertures, in a straightforward manner. In addition the notoriously thorny problem of partial coherence is adequately dealt with and the transition from wave optics to ray optics obtains in a smooth and seamless fashion.
