use a screen of tiny lenses. Spherical segments should be pressed into a sort of film with photographic emulsion on the other side. The screen would be placed inside a lightproof holder and on a tripod for stability. When exposed each tiny lens would function as a camera and record the surroundings from a slightly different angle than neighboring lenses. When developed and lit from behind the lenses should project the life-size image of the recorded subject in space. He could not yet present concrete results in March 1908, but by the end of 1908 he claimed to have exposed some Integral photography plates and to have seen the "resulting single, full-sized image". However, the technique remained experimental since no material or technique seemed to deliver the optical quality desired. At the time of his death in 1921 Lippmann reportedly had a system with only twelve lenses. Eugène Estanave performed further experiments with Lippmann's technique. He exhibited an integral photograph in 1925 and published about his findings in La Nature. In 1930 he had 432 lenses in a 6.5 x 9 cm plate with viewable results, but then abandoned the lenticular screen and continued his integral photography experiments with pinholes. Louis Lumière worked on integral photography and corresponded with Lippman about the technique. Lumière patented a system a few years after Lippmann's death, but never seems to have actually manufactured lenticular screens. Integral video 2010 Japan's NHK broadcasting company and Toshiba each showed a demo featuring a prototype display view-able with a 25 degree window. 2015 "Looking glass factory" started work on their multiscopic display, the latest is based around an 8k screen showing 45 different possible angles simultaneously See also Autostereoscopy Lenticular printing Focus stacking Plenoptic camera 3D display Stereoscopy References External links The History of Integral Print Methods — Comprehensive history of integral imaging Diffraction Influence on the Field of View and Resolution of Three-Dimensional Integral Imaging 3D imaging French inventions
