Holography is the science of recording three-dimensional information on a piece of two-dimensional film. It does this by recording the light that is scattered from an object in such a way that this pattern of light can be reconstructed when the hologram is viewed. The word holography comes from the Greek words holos, meaning “whole,” and gramma, meaning “message.” Holography is one of several techniques for representing images of objects in three dimensions that are attractive to science communicators working in science centers, museums, and similar institutions. In addition, teaching about holography provides an opportunity to convey important concepts in physics.
