Abstract: A system for correcting the trajectory of a projectile so that it reaches a designated target. The system comprises an optical radar comprising a laser emitting in the infrared band that makes it possible, in association with a processing device, to follow the movements of the target and of the projectile at the same time. The pieces of information given by the processing device enable a computer to calculate corrections to be made to the trajectory of the projectile in a final stage so that it meets the target. By modifying the trajectory of a projectile, such as a self-propelled missile or a shell, launched towards a target, the projectile can be made to hit a moving target or pass by at a reasonable distance that is small enough for the explosion provoked by its charge to definitely destroy the target.

Abstract: The device to control the direction of a light beam comprises mainly the following elements substantially aligned in the direction of a laser beam emitted by a source: a low-deflection, controlled deflection device; a holographic multiplexer comprising several recorded zones and giving several possible deflections depending on the direction of the beam that it receives;a system of shutters enabling the choice of the direction of the laser beam to be transmitted.
