Abstract
Abstract A real time illusion transmitter for transmitting three dimensional illusions of an object comprising a first parabolic mirror for producing a real image of an illuminated object, image detection means disposed in a position to receive said real image and adapted to generate video signals for transmission by cable or electromagnetic means, a second parabolic mirror located at a remote site and having associated therewith an image projector for producing an image from signals transmitted from said first parabolic mirror; said image projector projecting an image normal to the principle axis of the parabolic mirror to produce an illusion of the image when reflected from the parabolic mirror.

Claim 1
Independent Claim
208 words
A three dimensional illusional television system for transmitting an illusion of an object comprising: an image transmitter, said image transmitter including a first concave mirror having a focal point and center of curvature for producing real images of an object, an object field disposed about the principle axis of the concave mirror beyond the center of curvature of the concave mirror, an image field disposed about the principle axis and between the center of curvature and focal point of the concave mirror, and image detection means for generating electronic signals from said reflected real images; a facsimile transmitter for receiving said electronic signals from the image detection means and transmitting said received signals to an image receiver, and; an image receiver, said image receiver including a second concave mirror having a principle axis, focal point, and center of curvature; a second object field disposed about the principle axis and between the focal point and the center of curvature of said second mirror; and a video image projector disposed in the object field for projecting light rays onto the concave mirror, said projector including means for receiving electronic signals from said facsimile transmitter and producing an image therefrom whereby an illusional image may be viewed beyond the focal point.
Claim 2
Dependent Claim

A three dimensional illusional television system for transmitting an illusion of an object comprising: an image transmitter, said image transmitter including a first concave mirror having a focal point and center of curvature for producing real images of an object, an object field disposed about the principle axis of the concave mirror beyond the center of curvature of the concave mirror, an image field disposed about the principle axis and between the center of curvature and focal point of the concave mirror, and image detection means for generating electronic signals from said reflected real images; a facsimile transmitter for receiving said electronic signals from the image detection means and transmitting said received signals to an image receiver, and; an image receiver, said image receiver including a second concave mirror having a principle axis, focal point, and center of curvature; a second object field disposed about the principle axis and between the focal point and the center of curvature of said second mirror; and a video image projector disposed in the object field for projecting light rays onto the concave mirror, said projector including means for receiving electronic signals from said facsimile transmitter and producing an image therefrom whereby an illusional image may be viewed beyond the focal point.
