Engineers from the Electronics and Telecommunications Research Institute in South Korea have created the world’s first 3D holographic processor.
This technology allows converting ordinary 2D video into 3D holograms virtually in real time. The programmable digital holographic media processor (RHP) is based on a semiconductor using FPGA (Field Programmable Gate Array) technology.
The processor uses high-bandwidth memory (HBM) to create full-fledged color 3D holograms with 2D video. Its hardware is integrated into a single system-on-chip (SoC).
This processor extracts the primary colors — red, green, and blue from the 2D video and also reads the depth information of the 2D video, reproducing this data in 4K resolution with a maximum delay of 30 milliseconds. The device is capable of rendering holograms with a processing speed of up to 30 frames per second.
The RHP is capable of performing complex wave propagation calculations, converting 2D video into 3D holograms. Thanks to the use of high-performance HBM memory instead of DDR memory, the processor provides high processing speed for large-scale holographic computations of complex numbers.
As part of the demonstration, the processor developers confirmed that RHP allows for the smooth conversion of any video from a computer screenwhether it’s YouTube/Netflix content or video calls, to holographic 3D video.
The developers do not plan to stop there and want to improve this technology by making it possible to creation of holograms based on natural light and high-definition hologram visualization methods. The technology was demonstrated at SID Display Week I-Zone in 2023 and at SID Display Week 2024 in San Jose, USA.
«Our goal is to develop a dedicated holographic media processor chip (ASIC) for general-purpose holographic displays by utilizing hardware-based holographic image enhancement technology in the future», — explains Kwon Won Ok, Chief Scientist of ETRI’s Digital Holography Research Department.
