Abstract

We report on interferometric measurements of the figure error of an ultra-precise mirror with the shape of an elliptical toroid for the diffraction limited focusing of hard x-rays from an undulator x-ray source. We describe measurement configurations using Fresnel type holograms and photon sieves, and evaluate the measurement uncertainty.
