High-contrast, speckle-free, true 3D holography via binary CGH optimization
Scientific Reports, 2022 Holography is a promising approach to implement the three-dimensional (3D) projection beyond the present two-dimensional technology. True 3D holography requires abilities of arbitrary 3D volume projection with high-axial resolution and independent ...

Journal of High Energy Physics, 2010 Aging phenomena are examples of `non-equilibrium criticality' and can be exemplified by systems with Galilean and scaling symmetries but no time translation invariance. We realize aging holographically using a deformation of a non-relativistic version of gauge/gravity duality.

Recent advances in multi-dimensional metasurfaces holographic technologies
PhotoniX, 2020 Holography has attracted tremendous interest due to its capability of storing both the amplitude and phase of light field and reproducing vivid three-dimensional scenes. However, the large pixel size, low resolution, small field-of-view (FOV) and limited

Multi-freedom metasurface empowered vectorial holography
Nanophotonics, 2022 Optical holography capable of the complete recording and reconstruction of light’s wavefront, plays significant roles on interferometry, microscopy, imaging, data storage, and three-dimensional displaying.

Monthly Notices of the Royal Astronomical Society, 2008 The dynamic spectrum of a radio pulsar is an in-line digital hologram of the ionized interstellar medium. It has previously been demonstrated that such holograms permit image reconstruction, in the sense that one can determine an approximation to the complex electric field values as a function of Doppler shift and delay, but to date the quality of the ...

Holostereosynthesis: An Improvement to Louis Lumière’s Photostereosynthesis Technique
Applied Sciences, 2022 In 1920, Louis Lumière, one of the fathers of Cinématograph, invented photostereosynthesis, a photography technique that could recreate three-dimensional images without a specific artifice.
