摘要： A real image projection system includes at least one curved reflector, positioned in a tilted configuration, wherein an optical axis of the reflector is not coincident with a viewing axis, and a beampath between a target source and the curved reflector neither passes through nor reflects off of a beamsplitter.

摘要： A real image projection system comprising two or more optical surfaces of revolution, with at least one comprising an aspheric surface of revolution. The aspheric surface of revolution is of a design to reduce natural aberrations inherent in imaging using surface of revolutions of the conic family of curves. In one embodiment, a real image projection system includes a pair of curved reflector segments of the conical family of curves, wherein at least one of the reflector segments has an aspherical surface of revolution, the primary segment being of longer focal length relative to the secondary segment, and an object positioned substantially at the focal point of the longer focal length reflector segment, such that a real image is positioned substantially at the focal point of the shorter focal length reflector segment, and the real image is projected along a viewing axis extending from the object positioned at the focal point of the primary reflector segment to the surface of the primary reflector segment, to the surface of the secondary reflector segment, to the focal point of the secondary reflector segment, to a viewer.

摘要： A photo-screen device for a real image projection system includes a transparent or semi-transparent material having a fixed or static image applied to the surface thereof, wherein the photo-screen is positioned so as to intersect a real image beampath of the real image projection device. In an alternative embodiment, a method for producing a photo-screen device for a real image projection system includes the steps of printing colors thereon in reverse order and positioning the photo-screen such that the non-printed side faces a viewer of the real image.
