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…
