Imaging Ionic Displacements Across Inclined Ferroelectric Domains by a Reciprocity Approach to 4D‐STEM

Small, EarlyView.
Four‐dimensional STEM comprises a vast portfolio of electron microscopy methods in one data set, conventional plane‐wave illumination TEM being one of them. Here, the principle of reciprocity is employed to produce true structural projections of misoriented ferroelectric domains at atomic resolution. By reciprocal TEM imaging from four‐dimensional STEM

Computer generated display holography

, 2017
Holografie je speciální zobrazovací metoda umožňující záznam vysoce realistického 3-D obrazu. Navíc má nespočet technických aplikací, například v mikroskopii nebo nedestruktivním testování. Holografie je dvoustupňovým procesem.

Towards zero-th order free, full field of view, computer generated holography

In this study, we investigate the removal of zero-order diffraction (ZOD) in computer-generated holography (CGH) using a destructive interference approach.

Precise Nanoscale Mapping of Electric Fields Across Random Grain Boundaries in Polycrystalline Oxides Using Precession‐Assisted 4D‐STEM

Small, EarlyView.
Correlative singular value decomposition 4D‐STEM analysis of the potential, electric field, and charge density distributions with crystal orientation, strain across grain boundaries in polycrystalline materials. ABSTRACT Space charge layers (SCLs) at grain boundaries play a crucial role in modulating electric fields and thereby influence functional ...

Energy‐Resolved Localized Surface Plasmon Resonances With Non‐Monochromated STEM‐EELS Assisted by Multivariate Analysis

Small Methods, EarlyView.
Transmission Electron Microscopy is a powerful technique, able to provide morphological, chemical, and optical/electronic information, yet some of these features require the use of highly expensive machines such as monochromated microscopes. In this work, we used low dose, low voltage, and mathematical treatment to gain energy resolution in an ...

Hyperspectral and Multispectral Image Fusion via Deep Generalised Linear Mixed Model

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Hyperspectral–multispectral image fusion is an incomplete information fusion problem, and directly embedding information can lead to modality‐specific responses and cause spectral distortion, whereas the strong interband redundancy of hyperspectral images makes full‐dimensional fusion inefficient.

Computer Generated Holograms

, 2010
The presented Diploma thesis deals with the computer-generated diffractive structures or rather called computer generated holograms (CGH). We follow basic principles of classical holography and in the context of which we define a synthetic holography. We
