Fourier-transform holography with coherent hard X-rays

Experimental results of recording Fourier-transform holograms using 14 keV synchrotron radiation are presented. A Fresnel zone plate was used as a beam splitter to realize a submicron reference point source by its first diffraction order and at the same time a object wave by the transmitted zero order beam. The holograms were recorded by a high resolution CCD-camera and were numerically reconstructed afterwards.
