Scientist: Holographic television to become reality

Picture this: you're sat down for the Football World Cup final, or a long-awaited sequel to the "Sex and the City" movie and you're watching all the action unfold in 3-D on your coffee table.

It sounds a lot like a wacky dream, but don't be surprised if within our lifetime you find yourself discarding your plasma and LCD sets in exchange for a holographic 3-D television that can put Cristiano RonaldoRonaldo in your living room or bring you face-to-face with life-sized versions of your gaming heroes.

The reason for renewed optimism in three-dimensional technology is a breakthrough in rewritable and erasable holographic systems made earlier this year by researchers at the University of Arizona.

Dr Nasser Peyghambarian, chair of photonics and lasers at the university's Optical Sciences department, told that scientists have broken a barrier by making the first updatable three-dimensional displays with memory.

"This is a prerequisite for any type of moving holographic technology. The way it works presently is not suitable for 3-D images," he said.

The researchers produced displays that can be erased and rewritten in a matter of minutes.
