Circular Polarized 3D Glasses
Polarized 3D glasses create the semblance of three dimensional photographs by prohibiting the light that reaches each eye, an example of stereoscopy. To present a stereoscopic motion picture, 2 pictures are projected superimposed onto the same screen thru orthogonal polarizing filters. The spectator wears low-cost glasses which also contain 2 orthogonal polarizing filters. As each filter passes only that light which is in a similar way polarized and blocks the orthogonally polarized light, each eye sees only its separately polarized image, manufacturing a 3-dimensional effect.
