Computer-generated holography using a digital signal processor

, 2019
We present an implementation of the One-Step Phase-Retrieval (OSPR) algorithm for computer-generated holography (CGH) using a digital signal processor (DSP).

High-efficiency, broadband, and low-crosstalk 3D holography by multi-layer holographic-lens integrated metasurface

APL Photonics
Holographic display is considered the holy grail of photorealistic three-dimensional (3D) visualization technology because it can provide arbitrary wavefronts related to the essential visual cues of 3D images.

Mixed-Scene Holographic 3D Display for Film and Television Visual Content Presentation: Zero-Order-Suppressed Single-Hologram Fusion and Parallax-Preserving Digital Resizing

Photonics
Mixed-scene holographic 3D display for film and television visual content presentation remains challenging because recorded digital holograms and computer-generated holograms (CGHs) are produced under different numerical and hardware constraints.

Sparse‐Aperture Quasi‐Achromatic Spintronic Terahertz Emitter Enabled by Binary‐Phase Metasurface and Multi‐Spectral Intensity Optimization

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
We propose a sparse‐aperture shared‐aperture design with multispectral intensity optimization, enabling a Pt/W binary‐phase metasurface directly integrated with a spintronic emitter. The device achieves quasi‐achromatic focusing across 1.0–1.5 THz, with intensity fluctuation below 33% and edge preservation above 0.68.

Role of perceptually guided image quality metrics in computer-generated holography [PDF]

Computer-Generated Holography (CGH) algorithms relies on pixel-wise evaluation metrics for calculating holograms. Our work addresses a gap in the literature by evaluating various combinations of conventional pixel-wise metrics such as L2-norm and ...

Conversion of 2D picture to color 3D holography using end-to-end convolutional neural network

PhotoniX
In the field of holographic 3D display, generating a three-dimensional (3D) computer-generated hologram (CGH) from a single two-dimensional (2D) image has been a significant challenge due to the high-dimensionality of the problem.
