Abstract
This paper describes methods of predicting the degradation of the performance of a simple imaging system in terms of the statistics of the shape errors of the focussing element, and conversely, of specifying those statistics in terms of requirements on image quality. Results are illustrated for normal-incidence x-ray mirrors having figure errors plus conventional and/or fractal finish errors.
