Understanding topographic scatter has been the subject of many publications. For optically smooth surfaces that scatter only from roughness (and not from contamination, films or bulk defects) the Rayleigh-Rice relationship resulting from a rigorous e

The Rayleigh Rice vector perturbation theory has been successfully used for several decades to relate the surface power spectrum of optically smooth reflectors to the angular resolved scatter resulting from light sources of known wavelength, incident

The residual surface roughness of diamond-turned optics is expected to contain significant periodic components. The optical properties of such surfaces are explored as a special case of Rayleigh-Rice vector scattering theory applied to periodic rough

The frequency footprint of ID and 2D profiling instruments needs to be carefully considered in comparing ID surface roughness spectrum measurements made by different instruments. Contributions from orthogonal direction frequency components can not be

Great improvement has been made in the past several years in the quality of optical components used in synchrotron-radiation (SR) beam lines. Most of this progress has been the result of vastly improved metrology techniques and instrumentation permit

This paper reports on the development of a deterministic method of specifying the finish glancing-incidence mirrors in terms of their imaging performance. As a first step we have calculated the two-dimensional intensity distribution in the focal regi

As part of a project to develop methods of placing highly reflective multilayer coatings on the inside of Wolter I mirrors, we have been pursuing a program of measuring flat mirrors. These flats have been produced and examined at various stages of th

This paper derives the Mueller scattering matrices for two topographic scattering models--the Rayleigh-Rice or perturbation model and the geometrical-optics or facet model. The results are used to predict the polarimetric properties of the `haze' on

In the smooth-surface limit, the angular distribution of the intensity of light reflected and scattered from a rough surface depends only on the root-mean-square value of its surface roughness and is independent of the details of the distribution of
