    a mirror in which the reflection of said enlarged virtual image can be observed;

    means for repetitively moving said mirror through a predetermined range of movement; and

    means for selectively illuminating said light-emitting elements as said mirror moves, to create a substantially planar, two-dimensional, enlarged virtual image, said light-emitting elements, first imaging optics and said mirror being positioned relative to one another and relative to said viewer'"'"'s eye so that substantially all of said virtual image can be simultaneously observed without requiring said display system to be moved relative to said viewer'"'"'s eye and so that said imaging optics and said mirror are small enough for use in a hand-held and a headgear-mounted device.
