In this paper, we present an interferometric method to measure the shape of X-ray wavefront and the slope error of optical elements using microfocus x-ray source. According to the fractional Talbot effect, we built an x-ray grating interferometer for

A microfocus X-ray grating interferometer (MFXGI) is proposed to measure the profile of the X-ray wavefront and slope error of X-ray optical elements. This device consists of a phase grating G1 to modulate the incoming wavefront and an absorption gra
