ABSTRACT:
An exemplary two-row design for a reduction/enlargement gradient index lens is provided. The gradient index fibers of each row are aligned in the length direction so that the fiber axis lies along respective symmetrical planes. These planes are tilted with respect to each other and with respect to a plane normal to the object and image planes by some small angle. The array images objects in an object plane onto an image parallel plane of a magnification dependent on the system parameter. In this configuration, the center fiber of one row is aligned such that a plane extending through the axis of the center fiber in the width direction of the lens makes a right angle with the object and image planes. A further characteristic of the two-row array is that adjacent fibers in adjoining rows are offset to provide the required contiguous image at the image plane and to optimize the exposure uniformly.
