Abstract

Methods of figuring fused fiber optic arrays to achieve optical image transforms unique to the medium are discussed. A number of concepts including image plane modification, linear and non-linear magnification, and image duplicator/combiners are described. Fused fiber optic arrays have been tapered and figured, using conventional grinding and polishing techniques that will magnify an image in approximately a distance of 1.5 times the major diameter without traditional spherical or chromatic aberration considerations. It has been observed that when a parallel fiber optic array is cut at an angle other than 90° to the optical axis, an elongation of the surface, and the resulting image plane, is realized. One dimensional magnifiers up to 10X have been constructed. An element was constructed that resulted in non-linear magnification from center to edge without the necessity of aspheric generation or polishing. Triplet construction con-taining one convex/convex element and two plano/concave elements utilized spherical curves exclusively. Magnification variations of 8X have been observed.
