Full-volume aberration-space holography

Simultaneous, diffraction-limited control of multiple optical beams is crucial for applications ranging from lithography to optogenetics, deep tissue imaging, and tweezer-based manipulation of cells, particles, or atoms. Despite the desire to address wider fields of view, deeper volumes, and increasingly-disordered media, spatially-varying aberrations ...

Wavefront-based holographic lens optical power model for augmented reality applications

Results in Physics
The use of holographic optical elements (HOEs) has grown significantly in recent years, particularly in augmented reality (AR) and see-through display systems. Among them, holographic lenses (HLs) have attracted special interest due to their versatility,

Quantitative holographic analysis in stallion spermatozoa following cryopreservation

Scientific Reports
This study employs Holographic tomography (HT) to examine structural and biophysical changes occurring during the cryopreservation of stallion sperm. HT is an advanced imaging technique that integrates digital holography with tomography to achieve three ...

Wedge holographic complexity in Karch-Randall braneworld

Journal of High Energy Physics
We investigate holographic complexities in the context of wedge holography, focusing specifically on black string geometry in AdS3. The wedge spacetime is bounded by two end-of-the-world (EOW) branes with intrinsic Dvali-Gabadadze-Porrati (DGP) gravity ...

High-space bandwidth product computer-generated holography using volume holography

, 1993
We suggest a method for coding high resolution computer-generated volume holograms. It involves splitting the computer-generated hologram into multiple holograms, each individually recorded as a volume hologram utilizing the maximal resolution available from the spatial light modulator.

Imaging Photonic Resonances within an All‐Dielectric Metasurface via Photoelectron Emission Microscopy

Advanced Photonics Research
Dielectric metasurfaces, through volume‐type photonic resonances, enable precise control of light‐matter interactions for applications including imaging, holography, and sensing. The application space of dielectric metasurfaces has extended from infrared

I $$ \mathcal{I} $$ -extremization for AdS4 black holes: master volume, free energy, and baryonic charges

Journal of High Energy Physics
In a previous paper, we proposed an entropy function for AdS4 BPS black holes in M-theory with general magnetic charges, resolving a long-standing puzzle about baryonic charges in three-dimensional holography and offering a prediction for the large-N ...
