Development of a Holographic Directional Volumetric Display

IEEE Access
In previous studies, we introduced a directional volumetric display which can project in multiple directions by superimposing different two-dimensional images in three-dimensional space.

Recent progress of atomic resolution holography: from point defects to defect complexes

Applied Physics Express
Atomic-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 ...

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 ...

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

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.

Speckle decorrelation in Ultrasound-modulated optical tomography made by heterodyne holography

, 2016
Ultrasound-modulated optical tomography (UOT) is a technique that images optical contrast deep inside scattering media. Heterodyne holography is a promising tool able to detect the UOT tagged photons with high efficiency.

Noise reduction of electron holography observations for a thin-foiled Nd-Fe-B specimen using the wavelet hidden Markov model

Applied Microscopy
In this study, we investigate the effectiveness of noise reduction in electron holography, based on the wavelet hidden Markov model (WHMM), which allows the reasonable separation of weak signals from noise.

Toward a consistent definition of holographic entanglement entropy in de Sitter space

Journal of High Energy Physics
We investigate a new definition of holographic entanglement entropy in the framework of static patch holography for de Sitter space. Using the replica trick and twist operator formalism, we derive an entropy functional in dS3 expressed through de Sitter ...
