3-D TVs are a work in need of progress

The evolution of the new developments in the method of photography known

as holography is making a big progress that three-dimensional television

might be a reality before 1984, as Mr Orwell’s predicted in a novel. If you

don't what's a hologram, a hologram is a recording of an interference pattern

reflected from an object. From this recording, the object can be reconstructed

visually in a three-dimensional form.

Television viewers are still waiting for the 3-D revolution. Although 3-D TVs

went on sale in the United States and elsewhere in 2010, they have yet to

take off. Most of these sets, require to have a special glasses or have limited

viewing angles, and none of them use a holography to create an illusion.
