A new paper just published in Physical Review Letters introduces our Unified Modulated Pattern Analysis (UMPA) method, which improves speckle tracking techniques by combining multiple measurements to increase resolution and sensitivity. In the paper we demonstrate that the method applies equally well to random (speckles) and regular (e.g. grating) patterns. An implementation of the method …

[bibshow file=http://www.soton.ac.uk/~pt1c15/publications.bib] Many months of hard work by Björn have paid off: the paper describing our ptypy package has now been published[bibcite key=Enders2016a]. Beyond the technical descriptions of the package’s inner workings, our paper introduces a new formalism meant to deal with the ever increasing complexity of ptychographic reconstruction algorithms. The package is free of …

Near-field ptychography has made its entry a few years ago as a promising alternative to other holographic techniques. The technique combines the concepts and experimental setup of full-field phase-contrast imaging with the robust phase retrieval principles of ptychography. To take one dataset, one simply needs to translate the sample with respect to a structured illumination. …

Our ptychography reconstruction package ptypy is now open-source and online! The package has come a long way since its debut at the cSAXS beamline at the Swiss Light Source. The difference map reconstruction algorithm was first implemented in matlab with contributions from Martin Dierolf, Andreas Menzel and Cameron Kewish. Its descendant is still in used …
