holography

Photographic technique that produces multidimensional images where all visual information from the object, its environment, and the space in which it is located is recorded by coherent light such as a laser beam. The holographic image, hologram, appears in an unrecognisable pattern until illumination by a coherent light organises it into a 3D representation of the original object. Holography can record light intensity but also the degree to which the wave fronts, components of the reflected light, are matched to each other.
