Progress in X-Ray Inline Holography Phase Retrieval — •Marco Stockmar¹, Pierre Thibault¹, Martin Dierolf¹, Björn Enders¹, Andreas Fehringer¹, Julia Herzen¹, Irene Zanette¹, Peter Cloetens², and Franz Pfeiffer¹ — ¹Department of Physics (E17) and Institute of Medical Engineering (IMETUM), Technische Universität München, Germany — ²European Synchrotron Radiation Facility (ESRF), Grenoble, France

We present first numerical and experimental results obtained at a Synchrotron light source of an advanced X-ray inline holography phase retrieval method for high resolution nondestructive 2D and 3D imaging. Unlike existing methods, which are based on limiting constraints such as weak phase or absorption, our new method retrieves the full complex-valued transmission function of any object while eliminating reconstruction artefacts from imperfect wavefronts. This allows for imaging of a wide range of challenging samples inaccessible by existing methods.
