ABSTRACT:
An image projection system uses a projection screen formed over at least a portion of a spherical surface, with either a retroreflective or a directional-specific reflecting material, along with a beamsplitter and at least one lens-projector combination for each real image input to the screen. More than one different input image may be simultaneously used, either with each of the different images provided to a different area of the screen for providing juxtaposed real images to a single observer, or with each of the different real images being provided to a different observer. A non-spherical screen may be used if a retroreflective screen material is used in a system for providing simultaneous real images to spatially-separated plural observers.
