Compression Performance Analysis of Experimental Holographic Data Coding Systems

open access: yesSensors, 2023
It is challenging to find a proper way to compress computer-generated holography (CGH) data owing to their huge data requirements and characteristics. This study proposes CGH data coding systems with high-efficiency video coding (HEVC), three-dimensional

High-contrast, speckle-free, true 3D holography via binary CGH optimization

open access: yesScientific 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 ...

An exact construction of codimension two holography

open access: yesJournal of High Energy Physics, 2021
Recently, a codimension two holography called wedge holography is proposed as a generalization of AdS/CFT. It is conjectured that a gravitational theory in d + 1 dimensional wedge spacetime is dual to a d − 1 dimensional CFT on the corner of the wedge ...
