X-ray fluorescence holography

X-ray Fluorescence Holography (XFH) is a relatively new technique that benefits greatly from the coherent high-power X-rays available from synchrotron sources, such as the Japanese SPring-8 facility.

Fluorescent X-rays are scattered by atoms in a sample and provide the object wave, which is referenced to non-scattered X-rays. A holographic pattern is recorded by scanning a detector around the sample, which allows researchers to investigate the local 3D structure around a specific element in a sample.

It is useful for investigating the effects of irradiation on high temperature superconductors.
