An updatable holographic three-dimensional displayNature 451, 694-698 (7 February 2008) Holographic three-dimensional (3D) displays1, 2 provide realistic images without the need for special eyewear, making them valuable tools for applications that require situational awareness, such as medical, industrial and military imaging. Currently commercially available holographic 3D displays3 use photopolymers that lack image-updating capability, resulting in restricted use and high cost. |

Duality Stereoscopic Projection System |
The Duality 3D projection system provides affordable, high quality stereoscopic projection, allowing large audiences to watch immersive stereo 3D video using inexpensive passive polarizing glasses. Each system is tailored to meet individual requirements and can be supplied with front or rear screens in a wide range of screen sizes, ceiling or floor mounted. This type of 3D display sets the standard for effective 3D, surpassing all autostereo (glasses-free) systems, and is based on the same technique used in most 3D IMAX cinemas.
The Duality passive 3D projection system is based on a simple concept; integrating two low cost LCD or DLP projectors to achieve stunning 3D stereo images at a fraction of the cost of specialist active 3D projectors. The Duality system is suited to both real-time interactive visualisation and replay of stereoscopic 3D video. It is also suitable for projecting live 3D video from standard or high-definition cameras. Duality systems are available for purchase or rental.
