1. A display system for displaying a two-dimensional image, comprising:

  • a diffractive light-valve array, said light-valve array including a row of elongated, individually-operable, spaced-apart modulator members aligned parallel to each other, each of said modulator members for causing diffraction of light incident thereon to an extent determined by an operational state of said operable member;

    illumination means for causing light to be incident on said light-valve array;

    means for separating a diffracted portion of said incident light from a non-diffracted portion of said incident light;

    electronic means for operating said operable elements of said light-valve array to correspond to image-elements to be displayed;

    magnifying lens means for providing a magnified image of said light-valve array, via said separated diffracted, light portion, to a viewer; and

    scanning means, cooperative with said electronic means, for scanning said magnified image through the field of view of a viewer to represent sequential lines of the two-dimensional image, thereby causing said magnified image to appear to the viewer as the two-dimensional image.
