Visual perception of Fourier rainbow holographic display

Abstract

The rainbow hologram provides views of reconstruction with rainbow color within a large viewing zone. In our recent paper, a Fourier rainbow holographic display using diffraction grating and a white‐light LED source was introduced. In this technique, the rainbow effect is realized by the dispersion of white‐light source on diffraction grating, while the slit is implemented numerically by reducing the demands of the space‐bandwidth product of the display. This paper presents a novel analysis on the visual perception of the Fourier rainbow holographic display using Wigner distribution. The view‐dependent appearance of the image, including multispectral field of view and viewing zone, is investigated considering the observer and the display parameters. The resolution of the holographic view is also investigated. For this, a new quantitative assessment for image blur is introduced using Wigner distribution analysis. The analysis is supported with numerical simulations and experimentally captured optical reconstructions for the holograms of the computer model and real object generated with different slit size, reconstruction distance, and different observation conditions.

Evolutionary Quantum Technology: The Future with Holographic Plasma Voxel

“…Because of this, holographic display are developed, where the container used is air, as in figure 1 made by ref. [19][20][21][22][23][24][25][26][27][28][29][30]. The technique of making holograms is called holography, this technique has been widely used and developed by researchers, on ASTESJ ISSN: 2415-6698 the other hand the technology used is still not able to be used by the general public, because based on the size of the hardware and system it still requires a lot of development.…”
