Figure 1 discloses a gradient index lens array 10 comprising a plurality of gradient index fibers 10, lo2 .. 10 tilted with respect to their optical axes to provide a characteristic fanfold conbhguration. The array is positioned so as to transmit images from an object plane 12 to an image plane 14 at some magnification less than unity. The fiber array faces 16, 18 are circular and have centers of curvature which lie on the center line of the array. The faces of the fibers have been formed so as to provide a degree of curvature in a direction perpendicular to the length direction of the array as shown in Figure 2. The simplest case is to use sections of a circle; the faces of the array would then lie on a toroidal surface since a toroid is obtained mathmatically by rotating a circle and the planes containing the circle about a rotation point.
