Abstract

Imaging systems which utilize gradient index fibers in a lens array are inherently subject to a problem of non-uniformity of exposure of an image at an imaging plane. Figure 1 illustrates a configuration wherein the orientation of a lens array is changed relative to an object and image plane. In this figure, which shows a top view of the lens 4 through an object plane (not shown), the lens array is shown in an original position 40 which is vertically oriented in a first plane normal to the object and image plane 16 and in a new position 42 still normal to the object and image plane but now lying in a second plane separated to an angle 0 with respect to the
