Abstract

La présente invention concerne un procédé de purification impliquant : la détermination d'une localisation cible à atteindre par un matériau pulvérisé qui est pulvérisé à partir d'un dispositif de pulvérisation ; la détermination du fait ou non que le matériau pulvérisé entre en contact avec un objet durant l'intervalle à partir du moment où le matériau pulvérisé est pulvérisé par le dispositif de pulvérisation jusqu'à l'atteinte de la localisation cible, sur la base des informations de localisation d'objet obtenues par un premier capteur ; et la commande, sur la base des résultats de détermination, d'une manière telle que le dispositif de pulvérisation pulvérise le matériau pulvérisé dans une plage qui comprend la localisation cible.
