About Holography

♤ Holography is a technique which enables three-dimensional images (holograms) to be made. It records the light scattered from an object, and then presents it in a way that appears three-dimensional.

♤ Holography can be thought of as somewhat similar to sound recording, whereby a sound field created by vibrating matter like musical instruments or vocal cords, is encoded in such a way that it can be reproduced later, without the presence of the original vibrating matter.

♤ Holography has application in field of Art, Data storage, Sensors or biosensors, Security holograms and many more fields.
