WASHINGTON: Physicists will be looking at 3DTV in San Jose, Calif., come Oct. 11-15. That’s when the Optical Society’s annual meeting, “Frontiers in Optics,” or FiO, takes place at the Sainte Claire Hotel. Among the seriously high-tech stuff on the agenda, i.e., exawatt lasers and gigapixel cameras, 3DTV will be covered in a special symposium.

The OS said highlights will include:
- A keynote by Rod Archer, vice president of Cinema Products at RealD Inc., on 3D movie systems used for around 1,700 theater screens around the world.
- Martin Banks of the University of California, Berkeley discussing the difficulties of creating 3D images free of perceptual distortions that don’t cause headaches.
- Kevin Thompson of Optical Research Associates will lay out the future for the coming generation of head-worn displays, based on his work with Jannick Rolland of the University of Rochester's Institute of Optics.
- Masahiro Kawakita of NHK Science & Technology Research Labs in Japan will present an overview and a prototype 3DTV system based on integral photography technology.
- Gregg Favalora of Acutality Systems will present an overview of one type of 3D technology that moves away from glasses: volumetric displays, which project images onto high-speed rotating screens.
- Brian Schowengerdt of the University of Washington will describe a volumetric display that scans multiple color-modulated light beams across the retina of the viewer to form images of virtual objects with correct focus cues.
- Nasser Peyghambarian of the University of Arizona will present a prototype of a large-area 3D updateable holographic display using photorefractive polymers. The rewritable polymer material is a significant breakthrough for holographic display technology.

More information on FiO’s agenda is available at the OSA Web site.

: “Industry Forging Ahead with 3D Amid Questions”
“Some members fear de facto, non-open standards, for first-generation broadcast 3DTV will result from the technology decisions made by first providers. These are likely to be pay-TV operators, keen to differentiate their platform and consumer proposition. Technology decisions made by these players may not suit the current or future needs of free-to-air broadcasters.”
