Abstract

Figure 1 illustrates a typical configuration for a gradient index lens array imaging system. Array 10, comprising a plurality of fibers 12 is positioned intermediate parallel object and image planes 14 and 16. In the case where the object is not planar, for example, a CRT tube face 18, shown dotted, array 10 is no longer capable of providing the proper image. Figure 2 shows a modified lens arrav 20 wherein each of the fiber lengths 21, 22 have been modified in accordance with the equation:
