Overview

Hardware evaluation demonstrates real-time 4K multilayer holographic processing on an FPGA, indicating viability for immersive augmented reality and automotive displays.

Key Points

To develop a high-throughput, energy-efficient FPGA-based hardware architecture capable of generating real-time 4K multilayer computer-generated holograms from RGB-D video feeds.
Integrated high-bandwidth memory (HBM) with a single-step Fresnel diffraction formulation on an FPGA to alleviate 2D inverse fast Fourier transform (IFFT) memory bottlenecks.
Designed a hardware pipeline that converts streaming 4K RGB-D video packets directly into phase-only holograms for spatial light modulators.
Tested the system across 8-layer volumetric hologram configurations and live-streaming experiments at 30 frames per second.
Generated 4K 8-layer volumetric holograms at 30 frames per second with an end-to-end latency of 28 ms.
Reduced power consumption by 86% compared to conventional graphics processing unit (GPU) implementations.
Achieved stable full-color holographic reconstruction with accurate depth-focusing during real-time video streaming.
