Claim:
A scanning beam display system, comprising: a light source that produces a beam of light; a first beam scanner located in a plane to scan the beam of light along a first direction; a second beam scanner located in the plane to scan the beam of light received from the first beam scanner along a second direction different from the first direction; a screen having a display surface that is substantially perpendicular to and is located entirely on one side of the plane in which the first and second beam scanners are located, the screen being positioned to have one edge closer to the second beam scanner which scans the beam of light in beam directions that are not directed to the screen than to the first beam scanner; and an optical reflector located on the side of the plane where the screen is located and has one end positioned away from the screen, the optical reflector oriented to reflect the beam of light from the second beam scanner onto the screen along a folded optical path to scan the beam of light along the first and the second directions on the screen.
