got this from http://www.wisegeek.com/what-is-a-hologram.htm
Holograms are photographic images that are three-dimensional and appear to have depth. Holograms work by creating an image composed of two superimposed 2-dimensional pictures of the same object seen from different reference points. Holography requires the use of light of a single exact wavelength, so lasers must be used. In reflection holograms, the kind of holography that can be viewed in normal light, two laser beams and a photographic plate are used to take an image of the object.
