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.

Method and apparatus for correcting the aiming of an optical illuminator

An optical sighting device consists of a hood with two windows which can transmit radiation within predetermined wavelength ranges to a rotatable reflecting device. The reflecting device receives radiation from one or other of the windows and the hood is rotatable subject to the rotation of the reflecting device. The radiation reflected by the reflecting device is received by two dichroic mirror plates which are suitable for transmitting or reflecting thermal infra-red radiation, visible radiation and near infra-red radiation towards suitable corresponding detectors.
