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.
Claims15
An image projection apparatus including a lenticular screen having at least one lenticular face thereon, said screen comprising:
- (a) A plurality of clear transparent sections;
- and
- (b) a plurality of actinic filter sections laminately positioned alternately of said clear transparent sections, said filter sections being positioned at an angle to said lenticular face.
A planar optical viewing apparatus comprising:
- (a) a first sheet of clear, transparent material;
- (b) a plurality of courses of clear transparent material;
- and
- (c) a plurality of filters of actinic transparent material laminately positioned alternately of the clear transparent courses, the actinic transparent filters and the clear transparent courses being positioned at an angle to the clear transparent sheet.
A planar optical viewing apparatus comprising:
- (a) a first plurality of courses of clear transparent material having a first index of refraction;
- and
- (b) a second plurality of courses of clear transparent material having a second index of refraction laminately positioned alternately of the first plurality of courses to provide a thin, planar viewing apparatus.
A planar optical viewing apparatus comprising:
- A. a first plurality of courses of clear transparent material;
- and
- B. a second plurality of courses of birefringent material laminately positioned alternately of the first plurality of courses to provide a thin, planar viewing apparatus.
