Abstract

L'invention concerne la transmission d'énergie électromagnétique avec compensation de distorsion. Elle se rapporte à un ensemble optique cohérent d'adaptation fonctionnant à deux longueurs d'onde, formant un premier faisceau à une première longueur d'onde sur une cible, et tirant de ce faisceau une information sur des caractéristiques des perturbations de la phase, sur le trajet de propagation vers la cible. Un dispositif assure en conséquence la compensation de ces distorsions dans un second faisceau à une seconde longueur d'onde, transmis simultanément suivant le même trajet. Application à la correction de la phase des faisceaux électromagnétiques des lasers.
