ETRI (Electronics and Telecommunications Research Institute)
ETRI RHP (real‐time holography processor) is a fast and
efficient, scalable holographic video processor that uses
a layer‐based method employing a modified inverse
Fresnel transform. It is designed with a single‐layered
holography core using a fixed‐point model and
implemented on a field‐programmable gate array (FPGA).
The real‐time hologram processor features a 1k × 1k fast
Fourier transform and a 30 frames/sec conversion rate
in 4K color spatial light modulators after applying 2×
linear interpolation. It is capable of converting all
real‐time images on computer screens, such as those
found on YouTube and in movies, into holograms in
just 22 milliseconds.
