Electron tomography and holography in materials science
TLDR
An overview of the techniques of electron tomography and electron holography is presented and their capabilities with the aid of case studies that span materials science and the interface between the physical sciences and the life sciences are demonstrated.Abstract:
The rapid development of electron tomography, in particular the introduction of novel tomographic imaging modes, has led to the visualization and analysis of three-dimensional structural and chemical information from materials at the nanometre level. In addition, the phase information revealed in electron holograms allows electrostatic and magnetic potentials to be mapped quantitatively with high spatial resolution and, when combined with tomography, in three dimensions. Here we present an overview of the techniques of electron tomography and electron holography and demonstrate their capabilities with the aid of case studies that span materials science and the interface between the physical sciences and the life sciences.read more

Inhomogeneous spatial distribution of the magnetic transition in an iron-rhodium thin film.
Christophe Gatel,Bénédicte Warot-Fonrose,Nicolas Biziere,Luis Alfredo Rodriguez,Luis Alfredo Rodriguez,David Reyes,Robin Cours,M. Castiella,Marie-José Casanove +8 more
TL;DR: Using in situ heating and cooling electron holography to quantitatively map at the nanometre scale the magnetization of a cross-sectional FeRh thin film through the antiferromagnetic–ferromagnetic transition provides a direct observation of an inhomogeneous spatial distribution of the transition temperature along the growth direction.

High-purity free-electron momentum states prepared by three-dimensional optical phase modulation
TL;DR: In this article, a femtosecond-switchable inelastic beam splitter was demonstrated, where coherent optical phase modulation of 200-keV electrons at a thin electron-transparent membrane was used to prepare a high-purity three-dimensional momentum superposition state, which was characterized in energy and momentum space.

Reduced-dose and high-speed acquisition strategies for multi-dimensional electron microscopy
TL;DR: In this article, inpainting techniques are used to restore scanning transmission electron microscopy images in which a very restricted number of pixels are scanned, while compressed sensing tomographic reconstruction is capable of minimising artefacts due to angular subsampling.

TL;DR: In this article, a review highlights synchrotron X-ray fluorescence tomography, a well-established non-destructive technique that makes tomography richer by reconstructing the quantitative elemental distribution within samples down to the micrometer scale or even less.

Intensity-based holographic imaging via space-domain Kramers–Kronig relations
YoonSeok Baek,YongKeun Park +1 more
TL;DR: In this article, a phase image is obtained directly from a single intensity measurement in oblique illumination using space-domain Kramers-Kronig relations that transform the spatial variation in intensity to the spatial variations in phase.

Representation of a Function by Its Line Integrals, with Some Radiological Applications
TL;DR: In this paper, a method for finding a real function in a finite region of a plane given its line integrals along all straight lines intersecting the region was given, and the solution found is applicable to three problems of interest for precise radiology and radiotherapy: (1) the determination of a variable x-ray absorption coefficient in two dimensions, (2) the distribution of positron annihilations when there is an inhomogeneous distribution of the positron emitter in matter, and (3) a variable density of matter with constant chemical composition, using the energy loss

Iterative methods for the three-dimensional reconstruction of an object from projections
TL;DR: It is shown that in general ART produces erroneous reconstructions, and an alternative iterative method is proposed which will give correct reconstructions under certain conditions.
