Speckle based Dark field Imaging to map saxs signal

Speckle base imaging allows to quantify x-ray scattering by analyzing speckle defocus magnitude and direction. This analysis can be repeated at different x-ray propagation...基于散斑的成像（speckle-based imaging）可通过分析散斑的散焦幅度与方向，实现X射线散射（x-ray scattering）的定量表征。该分析可在不同的X射线传播条件下重复开展……
