Researchers analyze the performance of an holographic 3D display

Back in 2008, researchers from the University of Arizona have created a holographic 3D display that could write and erase images (which was a world's first). The key to the display was a photorefractive polymer material, which enabled the researchers to take advantage of the potential of holography to a greater extent than previously allowed. Now, in a follow-up study, the researchers have reported the results of their analysis on the performance of the display, including how the polymer enables display enhancements and what more needs to be done before such displays can be widely used.

The display they demonstrated was, at 4" x 4". It could display new images every 3 minutes, and images could be viewed for several hours without the need for refreshing. The researchers determined that improvements could be made by mechanisms such as pulsed writing and reflection geometry, with the ultimate goal of creating realistic 3D holographic applications.
