HOLOGRAPHY:: 

HOLOGRAPHY: Holography  is a technique which enables three-dimensional images to be made . It involves the use of a laser, interference, diffraction, light intensity recording and suitable illumination of the recording. It enables a light field Leith and Upatnieks (1962) applied laser light to holography. Dennis Gabor 1948

HOLOGRAM PROPERTIES:: 

HOLOGRAM PROPERTIES: If you look at these holograms from different angles, you see objects from different perspectives, just like you would if you were looking at a real object They usually just look like sparkly pictures or smears of color If you cut one in half, each half contains whole views of the entire holographic image.
