Surface magnetic field effects in local helioseismology

, 2007
Using helioseismic holography strong evidence is presented that the phase (or equivalent travel-time) of helioseismic signatures in Dopplergrams within sunspots depend upon the line-of-sight angle in the plane containing the magnetic field and vertical ...

Constructive holography

Journal of High Energy Physics
Abstract We consider the collective field theory description of the singlet sector of a free and massless matrix field in d dimensions. The k-local collective fields are functions of (d − 1)k + 1 coordinates. We provide a map between the collective fields and fields in the dual gravitational theory defined on AdS d+1 ...

Compressive Holography

Optics Express, 2009
Compressive sampling enables signal reconstruction using less than one measurement per reconstructed signal value. Compressive measurement is particularly useful in generating multidimensional images from lower dimensional data. We demonstrate single frame 3D tomography from 2D holographic data.

Wavelength-multiplexed orbital angular momentum meta-holography

PhotoniX
The field of high-bandwidth holography has been extensively studied over the past decade. Orbital angular momentum (OAM) holography, which utilizes vortex beams with theoretically unbounded OAM modes as information carriers, showcases the large ...

Resolving the Internal Magnetic Domain Structure of Cloudy Zone Tetrataenite

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Recent advances in magnetic imaging can directly capture the internal magnetization of natural and synthetic materials at resolutions <10 nm. This capability opens new possibilities to determine the magnetic domain state of ferromagnetic minerals that are fundamental for recording and retaining paleomagnetic records.

Pre-holography

Physical Review D, 2008
We construct a symplectic isomorphism, h, from classical Klein Gordon solutions of mass m on (d+1)-dimensional Lorentzian Anti de Sitter space (equipped with the usual symplectic form) to a certain symplectic space of functions on its conformal boundary (only) for all integer and half-integer Delta (= d/2 + (1/2)(d^2 + 4m^2)^{1/2}).

Waveguide‐Based Four‐Channel Crosstalk‐Free Metahologram Multiplexed by Diffraction Orders

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
A diffraction‐order‐multiplexed, four‐channel metahologram integrates a flat glass waveguide and an array of titanium dioxide nanopillars to realize crosstalk‐free holographic projection. Light undergoes total internal reflection within the waveguide and gets out‐coupled by diffraction from the nanopillar array.

High-efficiency, broadband, and low-crosstalk 3D holography by multi-layer holographic-lens integrated metasurface

APL Photonics
Holographic display is considered the holy grail of photorealistic three-dimensional (3D) visualization technology because it can provide arbitrary wavefronts related to the essential visual cues of 3D images.
