Recent advances in X-ray fluorescence holography

X-ray uorescence holography (XFH) provides three dimensional atomic images around specied elements. The XFH uses atoms as a wave source or monitor of interference eld within a crystal sample, and therefore it can record both intensity and phase of scattered X-rays. In this article, I show the theory including solutions for twin image problem, advanced measuring system, applications to dopants in silicon steel and shape-memory alloy related material, a new holographic method with X-ray excited optical luminescence.
