Formulation of perfect-crystal diffraction from Takagi-Taupin equations. Numerical implementation in the crystalpy library
Jean-Pierre Guigay, Manuel Sanchez del Rio
The Takagi-Taupin equations are solved in their simplest form (zero deformation) to obtain the Bragg-diffracted and transmitted complex amplitudes. The case of plane-parallel cryst…
X-ray focusing by bent crystals: focal positions as predicted by the crystal lens equation and the dynamical diffraction theory
Jean-Pierre Guigay, Manuel Sanchez del Rio
The location of the beam focus when monochromatic x-ray radiation is diffracted by a thin bent crystal is predicted by "crystal lens equation". We derive this equation in a general…
Translative lens-based full field coherent X-ray imaging
Carsten Detlefs, Mario A. Beltran, Jean-Pierre Guigay +1
We describe a full-field coherent imaging approach suitable for hard X-rays based on a classical (i.e. Galilean) X-ray microscope. The method combines a series of low-resolution im…
A finite element approach to dynamical diffraction problems
Ari-Pekka Honkanen, Claudio Ferrero, Jean-Pierre Guigay +1
A finite element approach to solve numerically the Takagi-Taupin equations expressed in a weak form is presented and applied to simulate X-ray reflectivity curves, spatial intensit…
X-ray Fourier ptychographic microscopy
H. Simons, H. F. Poulsen, J. P. Guigay +1
Following the recent developement of Fourier ptychographic microscopy (FPM) in the visible range by Zheng et al. (2013), we propose an adaptation for hard x-rays. FPM employs ptych…
