ABSTRACT:
The invention relates to the aiming of an optical illuminator on a target. The direction in which is seen the maximum light of the illuminator reflected by the target is detected, the angle formed by this direction and the direction of sight is measured and the result of this measurement is employed for controlling an orientation of the optical axis of the illuminator or of the optical axis of the sighting system, with the result that the direction in which is seen this maximum coincides with the optical axis of the sighting system. The invention is particularly applied to the sending of a moving body, provided with an optical, self-directing system, onto a target.
