Abstract

Surface flatness of optical elements like mirrors and multilayers may significantly influence on the experiments exploiting coherence properties of x rays. A wavy mirror surface can be considered as a random-phase object. In the article, brief notes on the coherence propagation downstream from a random-phase object are presented. Image formation of a wavy surface at grazing incidence is analyzed. An approach to the inverse problem solution of phase retrieval from the mirror images in coherent x rays is shown. A performed experiment demonstrates general consistency in surface topography obtained by means of x rays and LTP. The estimates on the coherence degradation due to surface roughness are obtained.
