A. Schropp,P. Boye,J. M. Feldkamp,Robert Hoppe,Jens Patommel,D. Samberg,Sandra Stephan,Klaus Giewekemeyer,Robin N. Wilke,Tim Salditt,J. Gulden,Adrian P. Mancuso,Ivan A. Vartanyants,E. Weckert,S. Schöder,M. Burghammer,Christian G. Schroer +16 more
TL;DR: In this article, the authors carried out a ptychographic scanning coherent diffraction imaging experiment on a test object in order to characterize the hard x-ray nanobeam in a scanning X-ray microscope and obtained a detailed quantitative picture of the complex wave field in the nanofocus with high spatial resolution and dynamic range.
Journal ArticleDOI
X-Ray Holographic Imaging of Hydrated Biological Cells in Solution
TL;DR: N nanoscale x-ray holographic imaging is demonstrated by imaging bacteria in the hydrated and living state, with quantitative phase contrast revealing dense structures of the bacterial nucleoids associated with compactified DNA.
Journal ArticleDOI
Hard X-ray imaging of bacterial cells: nano-diffraction and ptychographic reconstruction.
Robin N. Wilke,Marius Priebe,Matthias Bartels,Klaus Giewekemeyer,Ana Diaz,Petri Karvinen,Tim Salditt +6 more
TL;DR: 3D hard X-ray imaging of unstained bacterial cells by a combination of ptychography and tomography is presented and it is shown how the real and reciprocal space approach can be used synergistically on the same sample and with the same setup.
Journal ArticleDOI
Compound focusing mirror and X-ray waveguide optics for coherent imaging and nano-diffraction
Tim Salditt,Markus Osterhoff,Martin Krenkel,Robin N. Wilke,Marius Priebe,Matthias Bartels,S. Kalbfleisch,Michael Sprung +7 more
TL;DR: A compound optical system for coherent focusing and imaging at the nanoscale is reported, realised by high-gain fixed-curvature elliptical mirrors in combination with X-ray waveguide optics or different cleaning apertures.
