6. An improved guided missile with a laser guidance system having a laser that directs laser radiation in the general direction of a target that is subsequently reflected from the target back to the missile, a receiving lens mounted on the missile that receives the reflected laser radiation, wherein the improvement comprises:
a ferrule containing optical fibers divided into a plurality of pixels that receive the reflected laser radiation from the receiving lens, wherein each pixel in the plurality of pixels is provided a different pointing angle, relative to the image plane formed by the receiving lens, by arranging the fibers within the pixel such that the centroid of the field of view of the fibers is different from the centroids of the field of views of the other fibers in the other pixels; and
a plurality of optical sensors coupled to the optical fibers, each optical sensor being dedicated to a separate pointing angle and adapted to generate an electrical signal whose amplitude is responsive to the amplitude of the reflected radiation for the pointing angle that the optical sensor is dedicated to.
