Abstract:
A display system for producing modulated light which may be viewed by a viewer, the display system comprising:(a) a spatial light modulator including a light modulating medium switchable between different states so as to act on light in ways which form overall patterns of modulated light;(b) means for switching said modulating medium between said different states in a controlled way;(c) illumination means for producing a source of light; and(d) optics means for directing light from said source of light into said spatial light modulator and for directing light from said spatial light modulator through a predetermined source imaging area, said optics means cooperating with said illumination means and said spatial light modulator so as to produce a real image of said source of light within said source imaging area such that a virtual image of only said overall patterns of modulated light produced by said spatial light modulator is directly visible by said viewer from said source imaging area, said optics means including a curved surface beam splitter for directing at least a portion of the light from the source of light into the spatial light modulator.
