I. HistoryHolograms are three-dimensional images, which are diffraction patterns produced by a divided coherent radiation beam. They were discovered by Dr. Dennis Gabor in 1947 while he was working to increase the resolution of an electron microscope and discovered them completely by accident. Dr. Gabor named the holograms by combining the Greek words “holos” and “gramma,” which translates to “whole message.” 2 While traditional photographs are capable of recording only the amplitude and wavelength properties of light, resulting in a two-dimensional image, holograms, in addition to storing the amplitude and wavelength properties, are also capable of to memorize its phase properties. This additional property gives holograms their three-dimensional appearance and allows them to be viewed from many different angles. Holography was hampered for about a decade after its discovery due to the lack of a coherent light source. The solution came with the invention of the laser, which is capable of forming light waves with almost complete coherence. A laser could then be used to establish an interference pattern when reflections of its light from multiple points converge at a single point on a medium responsive to its light. Making holograms using this principle required elaborate setups to stabilize everything and isolate them from external vibrations, which made them difficult to create. These holograms are inherently static and do not allow for any interactivity. An improvement came in the form of multiplexed holograms, which contain the interference pattern of the same scene at different points in time. Depending on the viewing angle you can see a different image. Therefore, a view of the moving scene can be observed by rotating the hologram around its holder… in the center of the paper… the idea of ​​using holograms in museums as alternatives to artifact replicas. A highly detailed holographic image of the artifact could be created and used for static content. A computer-generated scene could then be created in the background, perhaps showing the artefact in its original environment. The interactive ability could then be used to display information about the artifact in the same view, thus creating an engaging environment for the viewer. Works Cited1 Bimber, O. (2004, January).
