RealD Cinema is a digital stereoscopic projection technology. It is the world's most widely used technology for watching 3D movies in theatres.[1] It does not require two projectors, unlike older film-based stereoscopic 3D projection technology. A high-resolution, digital cinema grade, video projector is used. The projectors use Texas Instruments' Digital Light Processing device or Sony's reflective liquid crystal display. RealD has an exclusive agreement with Sony to provide technology to project 3D movies with the Sony 4K projector.[2]
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. Linear polarization requires viewers to keep their head within a certain degree of tilt for effective 3D, otherwise they can 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
и вот такие очки (где там батарейки шторки и т п?)
давайте уже определимся сколько проекторов надо для 3д и какие очки - и самое главное - куды в кино идти )
