Researchers at Chiba University in Japan have developed a computer that can project high-quality three-dimensional (3D) holography as a video.

Chiba's Tomoyoshi Ito began working on specially designed computers for holography, called HORN (for HOlographic ReconstructioN), in 1992. The latest version, the HORN-8, which utilizes a calculation method called the "amplitude type" for adjusting the intensity of light, was recognized as the world's fastest computer for holography earlier this year.

With the newly developed "phase type" HORN-8, the calculation method for adjusting the phase of light was implemented, allowing the researchers to successfully project holographic information as a 3D video with high-quality images.

Said Ito, "We have been developing the high-speed computers for 3D holography by implementing the knowledge of information engineering and the technology of electrical and electronic engineering and by learning insights from computer science and optical methods."
