The displacement field in highly nonuniformly strained crystals is obtained by addition of constraints to an iterative phase retrieval algorithm. These constraints include direct space density uniformity and also constraints to the sign and derivatives of the different components of the displacement field. This algorithm is applied to an experimental reciprocal space map measured using high-resolution x-ray diffraction from an array of silicon lines, and the obtained component of the…

Retrieval of the atomic displacements in the crystal from the coherent X-ray diffraction pattern.

It is demonstrated that limiting the spatial variation of the first- and second-order spatial displacement derivatives improves convergence of the iterative phase-retrieval algorithm for displacements reconstructions to the true solution.

Coherent diffraction imaging (CDI) in the Bragg geometry has gained a niche in recent years for its ability to image strain in a crystalline lattice on the nanoscale. This development is based on the

Retrieving the displacement of strained nanoobjects: the impact of bounds for the scattering magnitude in direct space.

This work proposes the HIO(O(R))(M)+ER(M)-algorithm, which allows taking advantage of additional a priori knowledge of the local scattering magnitude and remedies HIO+ER's stagnation by incorporation of randomized overrelaxation at the same time.

Numerical study of Bragg CDI on thick polycrystalline specimens.

By using an object-lens distance shorter than the focal length, the numerical aperture is larger than in a traditional imaging geometry, and the setup is insensitive to small phase errors by lens imperfections, this paper expects to be able to achieve a spatial resolution smaller than 20 nm when using the objective lens in this configuration.

Invited article: a [corrected] unified evaluation of iterative projection algorithms for phase retrieval.

Iterative projection algorithms are successfully being used as a substitute of lenses to recombine, numerically rather than optically, light scattered by illuminated objects to allow aberration-free diffraction-limited imaging and the possibility of using radiation for which no lenses exist.
