Line 24:
Polarized light reflected from an ordinary motion picture screen typically loses most of its polarization, but the loss is negligible if a [[silver screen]] or [[aluminized screen]] is used. This means that a pair of aligned [[Digital Light Processing|DLP]] projectors, some polarizing filters, a silver screen, and a computer with a dual-head graphics card can be used to form a relatively high-cost (over US$10,000 in 2010) system for displaying stereoscopic 3D data simultaneously to a group of people wearing polarized glasses.{{Citation needed|date=January 2010}}
In the case of [[
Optical attachments can be added to traditional 35 mm projectors to adapt them for projecting film in the "over-and-under" format, in which each pair of images is stacked within one [[frame (film)|frame]] of film. The two images are projected through different polarizers and superimposed on the screen. This is a very cost-effective way to convert a theater for 3-D as all that is needed are the attachments and a non-depolarizing screen surface, rather than a conversion to digital 3-D projection. Thomson Technicolor currently produces an adapter of this type.<ref name="technicolor3d">{{cite web|url=http://www.thomson.net/GlobalEnglish/Deliver/Film/Technicolor-3D/Pages/default.aspx|title=Contact us – Technicolor Group|work=thomson.net}}</ref>
