Abstract

Very high spatial frequency irregularities with small amplitude on a polished surface that usually cause wide-angle scattering in conventional optical systems produce narrow-angle scattering in X-ray systems. Yet, even this small amount of scattering degrades the imaging properties of X-ray systems. Statistical surface perturbations and their effects on X-ray image quality are discussed. A model of surface roughness that is reasonably consistent with surface-profile measurements and visible-scatter-profile measurement is discussed. This model is then used to evaluate the image profile of an X-ray system.
