| Abstract: |
An apparatus and method for creating real image illusions utilizes a partially transparent scrim positioned between the real image and an optical system which produces the real image from a corresponding real object. When the scrim is illuminated by a light source or projector in front of and at an oblique angle to the scrim, the scrim forms a seemingly solid and non-transparent surface that conceals the optical system from view by an observer. The scrim also protects the optical system from damage and other vandalism, yet it does not distort or interfere with the light rays passing through the scrim to form the real image. The scrim also avoids distracting surface reflections, ghosting and other highlights.

I claim:
1. An apparatus for creating a real image illusion, comprising:
- (a) a selectively transparent screen having a plurality of apertures;
- (b) a real object source and a device behind the screen for producing light rays, corresponding to the real object source, which pass through the apertures in the screen and converge to form a real image in front of the screen; and
- (c) a light source for projecting light rays onto the screen and creating the appearance of a solid and non-transparent surface which prevents visual access behind the screen.
