Holographic Display

A research team has described a novel tabletop display system that allows multiple viewers to simultaneously view a hologram showing a full 3-D image as they walk around the tabletop, giving complete 360-degree access.

The paper was published this week in the journal Optics Express, from The Optical Society (OSA).

To be commercially feasible in a range of applications — from medicine to gaming to media — the hologram challenge is daunting. It involves scaling an electronic device to a size small enough to fit on a table top, while making it robust enough to render immense amounts of data needed to create a full-surround 3-D viewing experience from every angle — without the need for special glasses or other viewing aids.
