Leon M. Lohse, Anna-Lena Robisch, Mareike Töpperwien, Simon Maretzke, Martin Krenkel, Johannes Hagemann, Tim Salditt
2020 Journal of Synchrotron Radiation  
Importantly, the unified structure of the implemented phase-retrieval functions facilitates their use and performance test on different experimental data.  ...  A limiting factor in its development has been the phase-retrieval step, which was often performed using methods with a limited regime of applicability, typically based on linearization.  ...  This project is built on early initial work in phase retrieval and MATLAB code by Klaus Giewekemeyer and Matthias Bartels, who have pioneered holographic imaging in our group.  ...
