RealD Cinema is a digital stereoscopic projection technology made and sold by RealD Inc. It is currently the most widely used technology for watching 3D films in theatres.
RealD 3D cinema technology uses circularly polarized light to produce stereoscopic image projection. The advantage of circular polarization over linear polarization is that viewers are able to tilt their head and look about the theater naturally without seeing double or darkened images. However, as with other systems, any significant head tilt will result in incorrect parallax and prevent the brain from correctly fusing the stereoscopic images.
Because RealD 3D uses a single projector, it suffers a brightness disadvantage. The system causes "significant light loss"; RealD estimates the viewer sees about 35% of the light when viewing RealD 3D when compared to a similarly projected 2D image on a standard white screen.
The high-resolution, digital cinema grade video projector alternately projects right-eye frames and...
