Project lead Nasser Peyghambarian of the University of Arizona, who is also director of NSF's multi-institution Engineering Research Center for Integrated Access Networks (CIAN), explains the technology--a holographic system that can transmit a series of 3D images in near-real-time, a precursor to holographic videoconferencing.

A hologram of a member of Peyghambarian's lab appears in the photorefractive polymer screen. Moving the camera from side to side reveals what the researchers call parallax, one of the novelties of this research: The holographic image presents itself from different perspectives as the viewer moves his or her head from side to side or up and down.

This holographic representation of a vase shows different colors capable with the new system and an effect known as parallax, which makes the image life-like: As the viewer moves his or her head from side to side or up and down, the holographic image presents itself from different perspectives.
