, 2000 In-line particle holography is subject to image deterioration due to intrinsic speckle noise. The resulting reduction in the signal to noise ratio (SNR) of the replayed image can become critical for applications such as holographic particle velocimetry ...

Using a Dual‐wavelength Source for Depth Resolution Enhancement in Optical Scanning Holography
, 2011 We use a wavelength selectable source to demonstrate depth resolution enhancement in an optical scanning holography system. Sectional objects separated by 2.5μm in the axial direction are reconstructed with a Fourier‐domain conjugate gradient ...

Recent progress of atomic resolution holography: from point defects to defect complexes
Applied Physics ExpressAtomic-resolution holography, which uses X-rays or neutrons with wavelengths of about 1 Å, is a technique for visualizing three-dimensional local structures around specific elements, and its variations were demonstrated between 1990 and 2001 ...

Dramatic and Elusive Resonant Lattice Kerker Effect in the Nonlinear Response of Plasmonic Lattices
Nanophotonics, Volume 15, Issue 12, 25 June 2026.Plasmonic metasurface that supports the resonant lattice Kerker effect, manifesting as the suppression of reflection in a narrow spectral range due to the simultaneous excitation of electric dipole and quadrupole modes, also gives rise to a substantial near‐field enhancement.

Advanced Functional Materials, Volume 36, Issue 46, 8 June 2026.In this strategy, a conductive nano‐probe is employed to induce nanoscale phase transitions and map the nanoscale conductivity and trap density of GST films. By utilizing the contrasting properties of phase‐change states, nano‐resonators are fabricated that exhibit plasmonic conduction and dramatically different transport characteristics.

Annales Henri Poincaré, 2000 A rigorous (and simple) proof is given that there is a one-to-one correspondence between causal anti-deSitter covariant quantum field theories on anti-deSitter space and causal conformally covariant quantum field theories on its conformal boundary. The correspondence is given by the explicit identification of observables localized in wedge regions in ...

Development of a Holographic Directional Volumetric Display
IEEE AccessIn previous studies, we introduced a directional volumetric display which can project in multiple directions by superimposing different two-dimensional images in three-dimensional space.

Generating Circularly Polarized Light Using Hybrid Near‐Zero and High‐Index Materials
Advanced Photonics Research, Volume 7, Issue 6, June 2026.A flat‐optics approach to manipulating the polarization state of light is proposed using evanescent‐wave interactions in hybrid epsilon‐near‐zero and high‐index materials. The design enables linear‐to‐circular polarization conversion in a wavelength‐scale device design without depending on patterning or bulky optics and operates in both reflection and ...
