ABSTRACT 3-D television without glasses having horizontal parallax and operating over standard single channel bandwidth is implemented by using two television cam- eras aligned in the same plane, a 2:1 bandwidth compres- sion and a receiver that processes the two views one scan line at a time using successive element correlation within common scan lines to synthesize N views in- between the two received views. The television receiver/ projector contains an optical scanner with a central projection lamp, N + 2 small full frame Charge Couple Device Liquid Crystal Light Valve (CCDLCLV) television modulation array surfaces and is driven by N + 2 views of the scene. N + 2 views are sequentially projected by the optical scanner to a semi-specular screen that returns all projected light to a horizontally moving vertical aerial exit slit (having no physical properties) resulting in the accurate reconstruction of continuous scene horizontal parallax for simultaneous view by several observers.
