Abstract
A real image projection system is provided including a projection system housing with an aperture. This device provides a real image projected into a viewable volume of space relative to the aperture. An optical assembly and an object positioning device adjacent to the optic assembly provide the real image. The object positioning device may position an object adjacent to the optic assembly in dynamic or static fashion. The optical assembly receives the light rays reflected from the object and projects a real image of the object into the viewable volume of space. The invention provides environmental visual cues to promote perception of a three-dimensional image. The invention further includes a secondary mirror for use in reducing or minimizing the overall size of the system housing.
