Abstract
A process for making a real image of an object appear or disappear to an observer is disclosed. A real image projection system displays a real image of an object. A first polarizer and a second polarizer are utilized to control the appearance and the disappearance of the real image of the object to an observer. By changing the relative angular relationship between a first transmissive axis of the first polarizer and a first transmissive axis of the second polarizer, a real image of an object appears and disappears. In another aspect, a privacy film may be utilized to control the appearance and the disappearance of the real image of the object to an observer. An observer by traveling around the privacy film or the privacy film is rotated; a real image of the object appears and disappears to an observer.
