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) a writing arrangement that switches the modulating medium between the different states in a controlled way; (c) a light source; and (d) an optics arrangement that directs light from the light source into the spatial light modulator and directs light from the spatial light modulator through a predetermined source imaging area, wherein the optics arrangement cooperates with the light source and the spatial light modulator to produce a real image of the light source within the source imaging area such that a virtual image of substantially only the overall patterns of modulated light produced by the spatial light modulator is directly visible by the viewer from the source imaging area.
