    • Phase retrieval for object and probe in the optical near-field 

      Robisch, Anna-Lena (2016-01-12)
      Lensless, holographic X-ray microscopy is a non-invasive imaging technique that provides resolution on the nanometer scale. Therefore, a divergent, coherent and especially clean wavefront impinging on the sample is needed. ...

    • X-Ray Near-Field Holography: Beyond Idealized Assumptions of the Probe 

      Hagemann, Johannes (2017-11-08)
      All images are flawed, no matter how good your lenses, mirrors etc. are. Especially in the hard X-ray regime it is challenging to manufacture high quality optics due to the weak interaction of multi-keV photons with matter. ...
