Science and Technology: Lasers

Twenty years ago, scientists invented a new sort of light lasers. Now, as its breathtaking potential for visual entertainment is being realized, the laser is rapidly establishing itself as the world's most versatile industrial tool. As lasers develop their uses become more sophisticated; this program explores the widening world of the laser...holograms. Imagine a three-dimensional picture emerging from a two-dimensional glass plate. An optical illusion, yet utterly real...hologram. This beautiful new type of imagery is a form of photography which makes use of the very special nature of laser light. But holograms are much more than photographs with an extra dimension: their extraordinary properties will make them the basis of a completely new art form, and lead to a series of powerful new industrial techniques.
