U. engineers developing new hologram technology

SALT LAKE CITY — The future of 3-D technology is getting closer.A team of University of Utah electrical and computer engineers has developed a way to create full-color, 2-D and 3-D holograms that can eventually be used in a wide range of applications, including identification badges, credit cards and currency.Led by electrical and computer engineering associate professor Rajesh Menon, researchers developed holograms that are more realistic, brighter and could be viewed at wider angles than
