A system and method employing a push-pull modulator for stereoscopic image selection. The modulator includes a pair of surface mode liquid crystal cells having orthogonal rub axes, and a linear polarizer having absorption axis bisecting the orthogonal rub axes, and has high speed, good transmission, and symmetrical dynamic range characteristics. A field-sequential steroscopic video image may be transmitted from a video display screen (or video projector) through the modulator as the cells of the modulator are driven so that fields of alternately left-handed circularly polarized light and right-handed circularly polarized light will emerge. The transmitted circularly polarized light may be viewed using passive spectacles incorporating circular polarizing filters.
