X-ray phase imaging with a grating interferometer.
Timm Weitkamp,Ana Diaz,Christian David,Franz Pfeiffer,Marco Stampanoni,Peter Cloetens,Eric Ziegler +6 more
TL;DR: Using a high-efficiency grating interferometer for hard X rays (10-30 keV) and a phase-stepping technique, separate radiographs of the phase and absorption profiles of bulk samples can be obtained from a single set of measurements.

ANKAphase: software for single-distance phase retrieval from inline X-ray phase-contrast radiographs.
TL;DR: A computer program named ANKAphase is presented that processes X-ray inline phase-contrast radiographs by reconstructing the projected thickness of the object(s) imaged by using a single-distance non-iterative phase-retrieval algorithm described by David Paganin et al.
Time Resolved X-Ray Imaging of Dendritic Growth in Binary Alloys
TL;DR: In this paper, the authors used direct beam x-ray imaging, with intense coherent monochromatic synchrotron radiation and a fast readout low noise detector, for in situ studies of cellular and dendritic solidification of Sn-Pb alloys.

Interferometer for quantative phase contrast imaging and tomography with an incoherent polychromatic x-ray source
Christian David,Franz Pfeiffer,Timm Weitkamp +2 more
- 30 May 2006
TL;DR: An interferometer for X-rays, in particular hard X-ray, for obtaining quantitative phase contrast images, includes a standard polychromatic X ray source, a diffractive optical beam splitter other than a Bragg crystal in transmission geometry, and a position-sensitive detector with spatially modulated detection sensitivity as mentioned in this paper.
