Description: RealD 3D cinema technology is apolarized 3D systemthat usescircularly polarizedlight to producestereoscopic imageprojection. The advantage of circular polarization overlinear polarizationis that viewers are able to tilt their head and look about the theater naturally without seeing double or darkened images.[3]However, as with other systems, any significant head tilt will result in incorrectparallaxand prevent the brain from correctly fusing the stereoscopic images. The high-resolution,digital cinemagradevideo projectoralternately projects right-eye frames and left-eye frames, switching between them 144 times per second.[3]The projector is either aTexas InstrumentsDigital Light Processingdevice orSony's reflective LCOS (liquid crystal on silicon). A push-pullelectro-opticalliquid crystalmodulator called aZScreenis placed immediately in front of the projector lens to alternately polarize each frame. It circularly polarizes the frames clockwise for the right eye and counter-clockwise for the left eye.[4]The audience wearscircularly polarized glassesthat have oppositelypolarized lensesthat ensures each eye sees only its designated frame. In RealD Cinema, each frame is projected three times to reduce flicker, a system called triple flash. The source video is usually produced at 24 frames per second per eye (total 48 frames/s), which may result in subtleghostingand stuttering on horizontal camera movements. Asilver screenis used to maintain the light polarization upon reflection and to reduce reflection loss to counter some of the significant light loss due to polarization filter absorption. The result is a 3D picture that seems to extend behind and in front of the screen itself.
