Abstract
A light beam display employing interlaced light beam scanning comprising a display screen having a vertical and a horizontal dimension, a source of a plurality of light beams and an optical path including a movable reflector having a plurality of reflective facets between the display screen and the light beam source. The movable reflector directs the plural light beams to the display screen via one or more facets of the movable reflector to simultaneously illuminate plural different scan lines of the display which are spaced apart by plural non-illuminated scan lines. An optical mechanical element is provided for vertically shifting the light beams so as to illuminate different scan lines of the display screen.
