X-ray Holographic Data Set of 15 μm Spheres obtained at Petra III, P10, GINIX at DESY, Hamburg

<p>This is the data set presented in the article &quot;<strong><em>Phase Retrieval for Near-field X-Ray Imaging beyond Linearisation or Compact Support</em></strong>&quot;.</p> <p>It is a matlab file containing 3 fields:</p> <p>geometry contains&nbsp; the following fields: all distances z_01 (focus-sample) z_02(sample-detector) and derived quantites M (magnification), z_eff (effective propagation distance from Fresnel scaling), F (Fresnel number) and dxeff (effective pixelsize)</p> <p>images is a cell array of the 4 flat field corrected (not aligned nor magnified) measurements.</p> <p>p is a parameter structure. p.measurements contains the fully corrected data used for the reconstruction. p.F contains the rescaled Fresnel numbers - use these for reconstruction, corresponding to the order of measurements.&nbsp;&nbsp;</p>
