Recent advances in atomic resolution three-dimensional holography

Advances in Physics: X
Three-dimensional (3D) local atomic structure around specific functional atom plays a crucial role in functional materials, but it has not been able to be analyzed by a standard structure analysis method of x-ray diffraction (XRD) because this kind of ...

Multifunctional Metasurfaces for Bridging Terahertz Waves in Free Space and Waveguides

Advanced Physics Research, Volume 5, Issue 6, June 2026.
A multifunctional terahertz metasurface capable of simultaneous orthogonal polarization conversion and phase modulation is integrated onto a dielectric slab waveguide, thereby enabling efficient free‐space‐to‐guided‐wave coupling. By implementing tailored phase gradients on the metasurface, we demonstrate the formation of a focused spot within the ...

Relativistic and non-relativistic holography

, 2010
Holography is one of the most interesting developments in String theory in the past few years. In this thesis, we discuss various aspects of the correspondence at the phenomenological and conceptual levels.

Wave-front phase retrieval in transmission electron microscopy via ptychography

, 2010
There are many different strategies that allow the solving of the well-known phase problem corresponding to the loss of phase information during a physical measurement. In microscopy, and, in particular, in transmission electron microscopy, most of these

High‐Accuracy Thin‐Film Stress Sensor Exploiting Integrated Digital Image Correlation

Strain, Volume 62, Issue 3, June 2026.
A high‐accuracy Speckle Stress Sensor (SSS) is introduced for real‐time thin‐film stress measurements, combining integrated digital image correlation (IDIC) with dense overlapping spot patterns generated by a simple LED‐perforated plate setup. Unlike conventional multi‐beam optical stress sensors relying on detection of the centers of isolated laser ...

Multi‐Wavelength Achromatic 3D Meta‐holography with Zoom Function

Advanced Science
With the development of nanofabrication technology, meta‐holography has shown unprecedented potential for light regulation. However, due to the wavelength mismatch, chromatic aberrations are inevitable in multi‐wavelength meta‐holography. Moreover, since

Recent Developments in Deep‐Ultraviolet Flat Optics

Nanophotonics, Volume 15, Issue 10, 27 May 2026.
Deep‐ultraviolet flat optics (DUVFO) is emerging as a key platform for next‐generation photonics, enabling advanced functionalities beyond conventional DUV optics. This review outlines materials, devices, and system advances, highlighting wide‐bandgap platforms, while identifying key challenges in dispersion control, characterization, and wafer‐scale ...

Optical holography in dichromated gelatin

, 1987
Coupled wave theory is used to investigate the properties of high quality holograms recorded in dichromated gelatin. Initially, the properties of planar reflection gratings are studied in order to characterize the behaviour of the recording material in ...

Nested holography

Physical Review D
Recently, we introduced a symmetry on the structure of angular momentum that interchanges internal and external degrees of freedom. The spin-orbit duality is a holographic map that projects a massive theory in four-dimensional flat spacetime onto the three-dimensional S2×R null infinity.
