Glasses - free 3D : eventually someone is going to get this right , andresearchers in South Korea are well on their elbow room , which mean eventually we might be able to go to a 3D movie without having to tire out those dorky , uncomfortable glasses .
Now you wear specs in a movie like say , Avatar , so that two separate prototype can come together to create one 3D image . In the theater , there are two projector play two unlike picture show behind the interview , and the glasses aid you see them as one . To dump the spectacles , a projector would have to be behind the screen , and most theaters do n’t have the money or the equipment for that . Untilnow :
The fresh method acting would set aside movie theaters to keep their projectors where they ’ve always been , behind the audience , and use fairly simple optical engineering . A particular array sit in front of the projector and polarizes its light . A filter cover the projection screen then obscures dissimilar vertical area of the filmdom , like the slats of venetian blinds . Each of your eyes , sit at a slightly different slant , has some of the screen blocked and some of the filmdom visible . The movie has the right - eye and left-hand - center paradigm interleave in perpendicular columns with one another . The trick then is to have the Christ Within visible to your unexpended eye contain the odd - eye pixels and vice versa for the right middle .
Of course , 3-D has more problems than just cockamamie glasses ; it ’s also a horrible , garish novelty . But at least this elbow room your center - rolling wo n’t be hidden behind a stupefied brace of shades . [ Optics ExpressviaWired ]
