Computational load reduction by avoiding the recalculation of angular redundancy in computer‐generated holograms

ETRI Journal, 2019
A fast hologram calculation approach is proposed to reduce computational load by avoiding the recalculation of redundancy information. In the proposed method, the hologram is divided into several sub‐holograms that record and reconstruct different views ...

Digital Holographic Printing Methods for 3D Visualization of Cultural Heritage Artifacts

Digital Presentation and Preservation of Cultural and Scientific Heritage, 2014
Holography enables capture and reconstruction of the optical field scattered from three-dimensional (3D) objects. The hologram encodes both amplitude and phase of the field under coherent illumination, whereas photography records only the amplitude by ...

Reducing the memory usage of computer-generated hologram calculation using accurate high-compressed look-up-table method in color 3D holographic display.

Optics Express, 2019
In this paper, we propose an accurate high-compressed look-up-table method that uses less memory to generate the hologram. In precomputation, we separate the longitudinal modulation factors and only calculate the basic horizontal and vertical factors ...

Visual perception of Fourier rainbow holographic display

ETRI Journal, 2019
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

Real-time dynamic holographic display realized by bismuth and magnesium co-doped lithium niobate

Applied Physics Letters, 2019
Particular attention has been given to updatable or dynamic holographic displays in recent years. The absence of ideal recording materials hampered the realization of their commercial applications.
