Te parece sospechoso? Nosé, no termino de pillar el tono, aunque entiendo el contenido :-?
No lo se, a mi no, es lo que dice la advertencia de la wikipedia.
Technology
RealD 3D cinema technology uses circularly polarized light to produce stereoscopic images. Circular polarization is preferable to linear polarization because viewers are able to tilt their head and look about the theater naturally with no loss of 3D perception whereas linear polarization requires viewers to keep their head within a certain degree of tilt for effective 3D perception; otherwise they may see double or darkened images.[6]
The projector alternately projects the right-eye frame and left-eye frame 144 times per second, and circularly polarizes these frames, clockwise for the right eye and counterclockwise for the left eye. A push-pull electro-optical modulator called a ZScreen is placed immediately in front of the projector lens to switch polarization. The audience wears recyclable circularly polarized glasses to make sure each eye sees only "its own" picture, even if the head is tilted. In RealD Cinema, each frame is projected three times to reduce flicker, a system called triple flash. The source video is usually only (2x)24 frames per second (which can result in a subtle ghosting and stuttering on horizontal camera movements). A silver screen is used to keep the light polarized and to reflect back as much light as possible to counter polarization losses. The result is a 3D picture that seems to extend behind and in front of the screen itself.[7]
O sea, que es una pantalla especial, al menos en el hecho de que refleje más luz que una blanca. Me sigo preguntando si el hecho de que sea plateada no influirá en el hecho de que la onda salga con la poloarización adecuada... Tengo que investigarlo un poco.
Es una pantalla especial para que no destruya la polarización. Tengo que mirarme lo de polarización circular, no me acuerdo de eso.
Por cierto, lo que decíamos del argumento plano de Avatar: Yo decía que era un Bailando con Lobos. Otros han encontrado ciertas similitudes con Pocahontas (que no he visto)
