- Abstract
- In this paper, we present a fast and efficient scalable holographic video processor using a layer‐based method, which employs a modified inverse Fresnel transform. To verify the performance of the proposed architecture, we design a single‐layered holography core using a fixed‐point model and test its performance on a field‐programmable gate array. The implemented real‐time hologram processor features a 1k × 1k size fast Fourier transform and a 30 frames/sec conversion rate in 4K color spatial light modulators after applying 2× linear interpolation. All real‐time images on computer screens, such as YouTube and movies, are converted into holograms within 22 ms.
