Abstract

Abstract The disclosure is directed to an apparatus for receiving a plurality of two-dimensional images and for generating a three-dimensional display from these images. The plurality of two-dimensional images will typically represent different image planes of a desired three-dimensional image. The two-dimensional images may be still pictures, transparencies, motion pictures or images generated by any suitable means. In accordance with the invention, a plurality of flat screen fiber optical magnification units are provided. Each unit includes an input surface defined by the input ends of a multiplicity of fiber optical strands which extend rearwardly and then sidewardly from the input surface and terminate at their output ends which define an output surface that is perpendicular to the input surface. The strands of each unit are supported in a transparent support medium. The image magnification units are disposed one-behind-another with their output surfaces in substantially parallel relationship. Application of the two-dimensional images to the input surfaces of units effects display of a three-dimensional image. The rearmost fiber optical image magnification unit is formed with the fiber optical strands supported in an opaque supporting medium.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 121 words
Apparatus for receiving a plurality of two-dimensional images and for generating a three-dimensional display from said images, comprising: a plurality of fiber optical image magnification units, each unit comprising an input surface defined by the input ends of a multiplicity of fiber optical strands which extend rearwardly and then sidewardly from the input surface and terminate at their output ends which define an output surface that is perpendicular to the input surface, said strands being supported in a transparent support medium; said image magnification units being disposed one behind another with their output surfaces in substantially parallel relationship; whereby upon application of said two-dimensional images to said input surfaces a three-dimensional image is generated by the output ends of said strands.
Claim 2
Dependent Claim 121 words
Apparatus for receiving a plurality of two-dimensional images and for generating a three-dimensional display from said images, comprising: a plurality of fiber optical image magnification units, each unit comprising an input surface defined by the input ends of a multiplicity of fiber optical strands which extend rearwardly and then sidewardly from the input surface and terminate at their output ends which define an output surface that is perpendicular to the input surface, said strands being supported in a transparent support medium; said image magnification units being disposed one behind another with their output surfaces in substantially parallel relationship; whereby upon application of said two-dimensional images to said input surfaces a three-dimensional image is generated by the output ends of said strands.
