Application of Infrared Digital Holography for Characterization of Inhomogeneities and Voluminous Defects of Single Crystals on the Example of ZnGeP2

open access: yesApplied Sciences, 2020
In this work, the method of IR digital holography intended for detection of volumetric defects in ZnGeP2 single crystals has been tested. The holographic method is verified by a comparison of the results obtained with the data obtained by other methods ...

Carbonated Fluorapatite‐Gelatin‐Composites: Morphogenesis and Structure of Kniep's Dumbbells

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 11, 16 July 2026.
Inspired by the pioneering work of Prof. Rüdiger Kniep on fluorapatite‐gelatin nanocomposites also known as “Kniep's Dumbbells,” this study investigates carbonated fluorapatite‐gelatin aggregates synthesized by the double diffusion technique within a gelatin gel.

Noninvasive Intelligent Brain‐Metasurface System for Real‐Time Electromagnetic Wave Manipulation

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
A noninvasive intelligent brain–computer interface (BCI) is integrated with a reconfigurable metasurface to establish a direct neural‐to electromagnetic transduction pathway for real time, multimodal wave control. By combining convolutional‐neural‐network‐based decoding of motor‐imagery electroencephalography (EEG) signals with threshold‐based ...

Extending the Depth of Field beyond Geometrical Imaging Limitations Using Phase Noise as a Focus Measure in Multiwavelength Digital Holography

open access: yesApplied Sciences, 2018
Digital holography is a well-established technology for optical quality control in industrial applications. Two common challenges in digital holographic measurement tasks are the ambiguity at phase steps and the limited depth of focus.

Digital Holography and Cell Studies

open access: yes, 2011
Digital holography microscopy (DHM) has developed into a broad field, and one of all the interesting applications is to study cells without staining, labeling or in any other way affecting them. Both fixed and living, dying or dead cells can be studied. The first DHM images showing living cells were published in 2004 and 2005 (Carl et al. 2004, Marquet

Zooming algorithms for Digital Holography

open access: yesJournal of Physics: Conference Series, 2010
Digital Holography is an imaging modality made up of two parts: (i) Recording an interference pattern on a CCD, where an object wave field and a known reference wave are coincident and extracting the complex object wave field from this interference pattern and (ii) Replaying or reconstructing the hologram on a computer by simulating the propagation of ...
