holography

A technique for obtaining a stereoscopic image of an object without the use of lenses. It consists of recording on a photographic plate the pattern of interference between coherent light reflected from the object and light that comes directly from the same source (or is reflected from a mirror). The coherent light is usually provided by a laser. The photographic recording on the plate (called a hologram) when illuminated with coherent light yields an image that is identical in amplitude and phase distribution with the original wave from the object. It thus provides a three-dimensional image of the object in the sense that the observer's eyes must refocus to examine foreground and background and indeed 'look around' objects by simply moving the head laterally.

The hologrammatic image shows how the whole is not simply an abstraction in isolation from the parts.
