Holography: From Physics to The Big Screen Essay -- Cinematography

The technical evolution of film industry is one notable hold of modern civilization. The innovation of combining motion pictures with recorded sound. Black-and-white film gradually replaced by the colour motion picture film and the visual return involve the integration of live-action footage and computer generated imagery to create a scenes which look realistic, but would be dangerous, costly or impossible to be recorded and the popularisation of three-dimensional cinema. The developments of technique contribute the film industry to get closer to peoples perception, however, in the real life. The observation of objects would change if we look from dissimilar distance and angle. And this experience of perception butt endnot be done in film. Because of the lack of stereoscopic impression of film images, it limits our sense so that the actual we see exponent be different.In 1920s, Sergei Eisenstein had predicted that the future of cinematography was tridimensional and there are ma ny other film pioneers hold the same view. What most film histories leave tabu is that the Lumire Brothers were trying to achieve a three-dimensional image, Louis Lumire eventually re-shot LArrive dun Train with a stereoscopic film tv camera and exhibited it (along with a series of other 3D shorts) at French Academy of Science. The films were shot in two views of the scene and then printing the film in two different colors and combining them with layered film on one reel.S3D (Stereoscopic 3D) film with better use of polarization systems were invited in 1930s and shown in the public in 1950s, however, after this initial huge excitement, S3D films were not widely recognized. Although the polarized stereoscopic film technology have been improved in all possible... ...nounced that they veritable a generator of holograms on a board with a circuit that generates holograms on the LCD panel.The holography had demonstrated its potential. Now holograms are not so hostile future any more. The idea of the holographic movies started becoming popular among filmmakers. Andrei Tarkovsky said, The most important thing for cinema is for it to become holographic. A hologram basin be made not only with the light waves of a laser, but also with sound waves and other waves in the electro-magnetic spectrum. Acoustical holography can see through and through solid objects by using sound waves. Microwave holography detects images by recording the objects radio waves. Some holograms made with ultraviolet light can record an image of particle such as atom or molecule.Holography is one of the most significant discoveries humankind has ever made.
