Holograms Taken to New Dimension
University of Utah researchers have discovered a way to create inexpensive full-color holograms that are far more realistic, brighter, and can be viewed at wider angles than current holograms.

Researchers at the University of Utah say they have developed a method to create inexpensive full-color two- and three-dimensional (3D) holograms that are much more realistic, brighter, and able to be viewed at wider angles than current holograms.
The researchers say the technology could have a range of applications, including for currency, identification badges, amusement rides, and advertisements.
Using algorithms and a new fabrication method, the system redirects colors to appropriate locations, in order to project much brighter photographic images in two or three dimensions and with full, natural colors.
The holograms produced by the system can be viewed with regular white light, and from any angle without changing the image detail.
The technology also could be used to produce holographic photos or video, and moving 3D video could be possible in as little as two years, according to Utah professor Rajesh Menon.
