Abstract

One aspect of the invention relates to a laser ranging system. In this version of the invention, a guided missile (10) is provided with laser (not shown) 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 (101-104 or 616) is mounted on the missile that receives the reflected laser radiation. A ferrule (111-114) containing optical fibers divided into a plurality of pixels that receive the reflected laser radiation form the receiving lens, wherein each 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 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. A plurality of optical sensors (121A-D) 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.
