ABSTRACT:
An apparatus for producing a simulated three-dimensional psycho-image from a conventional two-dimensional image comprises a screen of transparent material having integral, alternate layers of materials with varying optical properties which enhance image contrast and provide an image bisection to produce an illusion of a three dimensional scene without the need for supplemental viewing glasses or similar devices. Alternate embodiments simulate Fresnel lens performance and provide color conversion.
