Called Cinema 3D, this technology uses mirrors and lenses to display a narrow range of angular images and replicate the same content to all seats in the cinema.
The Massachusetts Institute of Technology's Computer Science and Artificial Intelligence Lab (CSAIL) and Israel's Weizmann Institute of Science collaborated in bringing this new technology to theaters.
'Existing approaches to glasses-free 3-D require screens whose resolution requirements are so enormous that they are completely impractical,' MIT professor Wojciech Matusik, one of the co-authors on a related paper whose first author is Weizmann PhD Netalee Efrat, told MIT News.
'This is the first technical approach that allows for glasses-free 3-D on a large scale.'
Although glasses-free 3D technology isn't new, MIT's and Weizmann's system would pioneer an industry for cinemas.
The technology used in 3D TV sets consists of a series of slits in front of the screen (called a 'parallax barrier') that lets the viewer see a different set of pixels and creates a 'simulated sense of depth'.
However, this method isn't practical on a larger scale and comes at a cost of lower image-resolution.
To recreate this experience on a large screen, the team designed new physical projectors that cover the entire angular range of the audience.
Cinema 3D encodes multiple parallax barriers in a single display, which allows each movie-goer to see a parallax barrier tailored to their position – regardless if they are in the front row or all the way in the back.
The team's prototype screen consists of three optical layers: angle reduction elements, vertical lenslets, and slanted horizontal mirrors.
'The angle reduction elements improve the vertical resolution as they bend the rays emerging from each row of viewers towards the vertical lenslets, into a smaller angular range,' researchers share in the published study.
'This allows us to use a smaller vertical spacing.
The vertical lenslets are cylindrical lenslets designed to refract the vertical component of the rays toward the slanted mirrors.'
The slanted mirrors replace the slanted barrier, which, like the original barriers, provides rays from each viewer row with the right disparity.
That range of views is then replicated across the theater by a series of mirrors and lenses within Cinema 3D's special optics system.
