Real-Time Holographic Conversion From 2D Video

Researchers at the Electronics and Telecommunications Research Institute (ETRI) in Korea, operating under the National Research Council of Science and Technology (NST), have developed a field- programmable gate array (FPGA)-based processor capable of converting conventional 2D video into real-time 3D holograms.

This development addresses a computational bottleneck in the generation of dynamic digital holograms, where conventional general-purpose processors struggle to meet the latency and throughput demands of full-motion holographic display systems.

How it works

The real-time holographic media processor (RHP) integrates all computational units required for optical wavefront reconstruction into a single system-on-chip (SoC) architecture. Central to its performance is the inclusion of high- bandwidth memory, which replaces traditional double-data rate memory and significantly increases data transfer rates between the memory subsystem and processing logic. This is particularly important for real-time applications, where the reconstruction of holographic wavefronts from video requires rapid execution of complex- number arithmetic and Fourier- domain calculations.
