The stereoscope was first invented by Sir Charles Wheatstone in 1838. It showed that when two pictures are viewed stereoscopically, they are combined by the brain to produce 3D depth perception. The stereoscope was improved by Louis Jules Duboscq, and a famous picture of Queen Victoria was displayed at The Great Exhibition in 1851. In 1855 the Kinematoscope was invented. In the late 1890s, the British film pioneer William Friese-Greene filed a patent for a 3D movie process. On 10 June 1915, Edwin S. Porter and William E. Waddell presented tests in red-green anaglyph to an audience at the Astor Theater in New York City and in 1922 the first public 3D movie The Power of Love was displayed.
Stereoscopic 3D television was demonstrated for the first time on 10 August 1928, by John Logie Baird in his company's premises at 133 Long Acre, London.Baird pioneered a variety of 3D television systems using electro-mechanical and cathode-ray tube techniques. In 1935 the first 3D color movie was produced. By the Second World War, stereoscopic 3D still cameras for personal use were already fairly common. In the 1950s, when TV became popular in the United States, many 3D movies were produced for cinema. The first such movie was Bwana Devil from United Artists that could be seen all across the US in 1952. One year later, in 1953, came the 3D movie House of Waxwhich also featured stereophonic sound. Alfred Hitchcock produced his film Dial M for Murder in 3D, but for the purpose of maximizing profits the movie was released in 2D because not all cinemas were able to display 3D films. The Soviet Union also developed 3D films, with Robinzon Kruzo being its first full-length 3D movie, in 1946.
There are several techniques to produce and display 3D moving pictures. The following are some of the technical details and methodologies employed in some of the more notable 3D movie systems that have been developed.
The future of 3D television is also emerging as time progresses. New technology like WindowWalls (wall-size displays) and Visible light communication are being implemented into 3D television as the demand for 3D TV increases. Scott Birnbaum, vice president of Samsung's LCD business, says that the demand for 3D TV will skyrocket in the next couple of years, fueled by televised sports. One might be able to obtain information directly onto their television due to new technologies like the Visible Light Communication that allows for this to happen because the LED lights transmit information by flickering at high frequencies.
Health effects !!!!!
Some viewers have complained of headaches and eyestrain after watching 3D films.There have been several warnings, especially for the elderly.Motion sickness, in addition to other health concerns, are more easily induced by 3D presentations.
There are primarily two effects of 3D TV that are unnatural for the human vision: crosstalk between the eyes, caused by imperfect image separation, and the mismatch between convergence and accommodation, caused by the difference between an object's perceived position in front of or behind the screen and the real origin of that light on the screen.
It is believed that approximately 12% of people are unable to properly see 3D images, owing to a variety of medical conditions. According to another experiment up to 30% of people have very weak stereoscopic vision preventing depth perception based on stereo disparity. This nullifies or greatly decreases immersion effects of digital stereo to them.
