Holography

Name:
Holography
Detailed information:
Production of a unique three-dimensional image on photographic film by means of an interference pattern created by a laser beam that is split by a mirrorlike device. The beam is divided in such a way that one portion is reflected from the subject while the other forms a direct image; the resulting superimposition results in an unusual 3-D effect.

Use:

The technique has a number of practical applications in airplane flight control, missile guidance systems; other uses will undoubtedly develop.
