Abstract

We demonstrate use of a complex constraint based on the interaction of x-rays with matter for reconstructing images from coherent X-ray diffraction. We show the complementary information provided by the phase and magnitude of the reconstructed wavefield greatly improves the quality of the resulting estimate of the transmission function of an object without the need for a priori information about the object composition.

摘要

我们展示了基于X射线与物质相互作用的复杂约束在从相干X射线衍射重建图像中的应用。我们表明，重建波场的相位和幅度所提供的互补信息，在无需关于物体组成的先验信息的情况下，极大地提高了物体传输函数估计结果的质量。
