Wave-optical evaluation of reflected X-ray intensity and wavefront distribution in total reflection hard X-ray by mirror optics

Abstract

A wave-optical simulator was coded and applied to the predictions of reflected beam qualities such as profiles of intensity and wavefront phase. Reflected beam qualities of flat mirrors with artificial bumps, which were modeled by Gaussian functions having a height of 1nm and widths from 0.06mm to 54mm, are investigated in the case of relatively short distance from the mirror center to the observing point such around 1m-long. As a result, bumps with the widths around 1mm make high contrast interference fringes in the reflected beam. Simulated results are examined and confirmed to be in good agreements.
