An optical sighting system includes at least one optical channel with which there is associated at least one reticle. The reticle includes at least one mark which demarcates a blind spot, which is visible to an observer using the optical sighing system and which is centered approximately about a centering point that is situated substantially at a distance which is representative of a sighting angle of between 13&deg; and 18&deg;, with respect to a predetermined direction of observation along a first direction. This first direction is representative on the optical sighting system of the direction passing substantially by the centers of the eyes of an observer who is using the optical sighting system.

Optical sighting system

The present invention relates to a laser-scan process for guiding a missile (M) to a target (T), according to which one observes a field ( ), within which said missile (M) is liable to move, so as to locate the latter in said field ( ), as well as to a device for implementing said process. According to the invention, in said field ( ), a zone ( ) is determined around the instantaneous position of said missile (M) thus located, and the laser scan is performed solely in said zone ( ).

Laser-scan process and device for guiding a missile to a target

A device intended to be associated, on the one hand, with a viewfinder, on the eyepiece side thereof, and, on the other hand, with a calculating mechanism, to form a system making it possible to determine at every instant that portion of a field sighted by the eye of an observer through the viewfinder. The device is arranged on the image side of the eyepiece of the viewfinder and includes a splitter element associated with a thick optical plate whose parallel faces are orthogonal to the optical axis of the finder.
