    • A system for providing simulated three-dimensional viewing from a conventional movie screen, television, or computer monitor which enables the viewer to select either two-dimensional or three-dimensional viewing. The system comprises a video projector (20), a prism (30), a pair of optical filters, a reflecting mirror (50), and a viewing screen (60). The prism separates projected light from the source into two separate images. A film of polarized material is placed proximate to the prism so that the two images are linearly polarized orthogonally to one another. The two images are then directed to a mirror that is preferably polarized and then directed to a video screen. A pair of glasses containing lenses having polarizers parallel to the polarizations of respective images are provided.
    • 一种用于从常规电影屏幕,电视或计算机监视器提供模拟三维观看的系统,其使观看者能够选择二维或三维观看。 该系统包括视频投影仪(20),棱镜(30),一对滤光器,反射镜(50)和观察屏(60)。 棱镜将来自光源的投影光分离成两个独立的图像。 极化材料的膜被放置成靠近棱镜,使得两个图像彼此正交线性偏振。 然后将两个图像定向到优选极化的反射镜,然后被引导到视频屏幕。 提供了一对包含具有与各个图像的偏振平行的偏振器的透镜。
