Stereo television apparatus comprising, in combination: a projection television receiver for projecting light toward a screen as a sequence of images representative of a video signal comprising left and right video frames alternating at a predetermined frequency; apparatus dividing the light into first and second portions and directing the portions to fall successively on substantially the same area of the screen; and apparatus alternately rotating the planes of polarization of the portions in first and second opposite senses in synchronism with the predetermined frequency, so that when the screen is observed binocularly through eyepieces of oppositely rotated polarization, a stereo image is perceived by the observer. |
