Three-dimensional phase contrast imaging of multiply-scattering samples in X-ray and electron microscopy is extremely challenging, due to small numerical apertures, the unavailability of wavefront shaping optics, and the highly nonlinear inversion required from intensity-only measurements. In this work, we present a new algorithm using the scattering matrix formalism to solve the scattering from a non-crystalline medium from scanning diffraction measurements, and recover the illumination…

A Fast Algorithm for Scanning Transmission Electron Microscopy Imaging and 4D-STEM Diffraction Simulations
A new method for STEM simulation is introduced: partitioning of the STEM probe into “beamlets,” given by a natural neighbor interpolation of the parent beams, which can lead to even larger improvements in simulation time, as well requiring significantly less computer random access memory (RAM).

It is argued that a physically better justified ab initio description of the scattering potential is both useful and viable for an increasing number of systems, and it is expected that such simulations to steadily gain in popularity and importance.


Inversion of Many-Beam Bragg Intensities for Phasing by Iterated Projections: Removal of Multiple Scattering Artifacts from Diffraction Data.
An iterated projection algorithm (N-Phaser) is developed that reconstructs a scattering potential from N-beam multiple Bragg scattered intensities, and it is shown that the algorithm recovers accurate complex structure factors from a wide range of thicknesses, orientations, and relativistic beam energies.

Reference-less measurement of the transmission matrix of a highly scattering material using a DMD and phase retrieval techniques.
This paper shows that the transmission matrix of a highly scattering medium can still be retrieved, through signal processing techniques of phase retrieval, and is experimentally validated on three criteria : quality of prediction, distribution of singular values, and quality of focusing.
Relaxation of the Crowther criterion in multislice tomography.
It is shown here that if the imaging method used reconstructs Na planes along each viewing direction, one can reduce the number of illumination directions required to fill Fourier space by a factor of 1/Na, relaxing the usual Crowther criterion for tomography.
