ABSTRACT:
A compact display system including a viewing surface; a beam steering mechanism; a source of light remote from the viewing surface and the beam steering mechanism; and at least one waveguide connecting the source of light with the viewing surface for transmitting illumination from the source of light to the viewing surface. The beam steering mechanism is associated with the waveguide and the viewing surface for scanning illumination transmitted by the waveguide onto the viewing surface. There is a modulator for modulating the source of light; and a subsystem for synchronizing the modulator with the beam steering mechanism, but only the distal end of the waveguide and the beam steering mechanism are located near the viewing surface resulting in a more compact display which can be mounted on a pair of eyeglasses.
