Abstract
The disclosure pertains to an optical display apparatus, or fiber optics magnification panel, and a method of making same. In accordance with the disclosed method, a plurality of substantially parallel relatively closely spaced optically conducting elongated strands, such as fiber optic strands, are wrapped about a spacer element. At least one additional spacer element is then positioned over the previously wrapped strands and the plurality of strands is rewrapped over the at least one additional spacer element in spiral fashion. The operation of positioning an additional spacer element over the previously wrapped strands and rewrapping the strands over the additional spacer element is then repeated a desired number of times. The resultant spirally wound construction is then severed substantially along the plane of the first-mentioned spacer element, and a resultant portion of this severing operation is angularly severed to form a pair of wedge-shaped display panels.
