Japan Pledges 3D Holography for 2022 World Cup
May 20, 2010
Japan is betting it will have holographic TV technology ready in time to host
the 2022 World Cup soccer event. The
Japan Times said the country unveiled its bid for the 2022 World Cup on
Monday. Japan and South Korea would co-organize the event and employ 3D,
holographic display technology into the coverage.
“The high-tech projects include images being beamed onto giant 3-D
hologram-style flatbed screens, translation earpieces for fans of different
nations to converse with each other, and devices to instantly capture
information by pointing at players on the pitch,” The Times said.
Keio University’s Jun Murai is assisting in the development of the proposed
technology He said there were challenges to achieving full holography in 12
years, but that the research phase was completed. Functioning equipment is
expected as soon as 2016.
Indeed, Japan’s National Institute of Information and Communications
Technologies demonstrated crude electronic holography at the NAB show last
year. Here is what video expert Mark Schubin noted of that demo:
“On the reproduction end, it appears to be true wavefront reconstruction. Laser
beams are used just as they were in original holograms to reproduce the
wavefronts captured in the interference patterns of the holograms. Three lasers
were used for the three primary colors. The resulting hologram appeared to
float in space. It was tiny and had a limited viewing angle. It also suffered
not only from laser speckle but also from other noise.
“On the capture end, the system is not holographic. It uses something called an
‘integral camera.’ It is an ultra-high-definition camera--sometimes referred to
as 8K--shooting a normally lit scene through a ‘fly’s-eye’ planar array of
small lenses. A computer then processes the image into an interference-pattern
type hologram, using the wavefront information captured from the fly’s-eye lens
array. The interference patterns are then sent electronically, live except for
the processing latency, to three small liquid-crystal displays, which are
illuminated by the reproduction lasers.”
The Japan Broadcasting Corp. also showed a similar 8K integral camera at the
same trade show, he said. “But this time the image was projected directly
through another lens array onto a screen. Viewers needed no 3D glasses and
could move their heads to see around objects.
“Both NICT’s and NHK’s integral-camera demonstrations resulted in very crude
images. There is no technological reason, however, preventing future
