White-beam x-ray fluorescence holograms were recorded using a 50 watt x-ray tube for a Cu 3 Au single crystal. Element sensitivity for this model sample was explicitly demonstrated by measuring distinct holograms using Cu K and Au L x-ray fluorescence. The phase sensitivity of the recorded holograms enabled us to obtain projections of the local atomic structure and image the electron density within the unit cell, relative to either Au or Cu atoms. Since the experimental setup does not require any optics and the angular resolution requirements are loose, the application of more powerful laboratory x-ray sources is straightforward.
