摘要
We analyze the use of glancing angle Fresnel mirrors for the determination of the mutual intensity function of a partially coherent x-ray beam in both vertical and horizontal directions with variable glancing angle and by tilting one of the mirrors around the propagation direction. Analytical results are discussed in the limit of narrow mirrors and Gaussian coherence. (C) 1996 society of Photo-Optical instrumentation Engineers.
