Hologram

A hologram is a three-dimensional image created by a single laser beam which is split and splashed onto the object and projected outward from its origin point. The science of creating a hologram is called holography, a technique that allows the light scattered from an object to be recorded and later reconstructed so that it appears as if the object is in the same position relative to the recording medium as it was when recorded. The image changes as the position and orientation of the viewing system changes in exactly the same way as if the object were still present, thus making the recorded image appear three dimensional.
