Abstract: A laser source projects a main beam through a central hole formed in an optical wedge. A portion of the laser light is refracted through the wedge and forms an optical side lobe. By rotating the wedge the side lobe undergoes a conical scan enhancing the tracking capability of the laser beam. A laser range finder processes the reflected return of the conical scan from a target and establishes an error signal which is minimized when equal reflections are obtained at spaced points along the conical scan thereby establishing a tracking direction which is coincident with the optical center of the target.
