Large viewing angle holographic 3D display system based on maximum diffraction modulation

open access: yesLight: Advanced Manufacturing, 2023
An ideal holographic 3D display should have the characteristics of large viewing angle, full color, and low speckle noise. However, the viewing angle of the holographic 3D display is usually limited by existing strategies, which vastly hinders its ...

Holographic display of synthetic 3D dynamic scene [PDF]

open access: yes3D Research, 2010
A synthetic scene of real-word objects is obtained through the multiplexing of several digital holograms. Moreover, by an opportune numerical hologram deformation, it is possible to synthesize 3D dynamic scenes that can be displayed by means of a spatial light modulator.
