ABSTRACT:
A thin rectangular hollow-boxed viewing screen containing a thin, flexible, soft, convex Fresnel lens; is placed and aligned in front of a T.V. set. Audio sound waves are used to continuously vary the radius of curvature, the focal position, the angle of incidence, effective thickness and shape of the lens medium. All of these changes are made in a continuous and rapid manner that produces pseudo three-dimensional images from a two-dimensional source. The rectangular box-like viewing screen is simple in design and construction; economical to manufacture, easy to install and use, all with no changes or modifications to the television set required.
