Abstract

Ce procédé de marquage temporaire d’un objet (10 ; 18) en surface comporte une étape (104, 106) d’inscription d’un motif, porteur d’un code d’identification unique associé à cet objet (10 ; 18), dans une portion de la surface de l’objet formée d’un matériau constitutif prédéterminé (14). L’inscription (104, 106) du motif comporte l’émission (106), à l’aide d’un dispositif (16) d’émission à accélération de particules, d’un faisceau de particules chargées vers chaque point de surface du motif à inscrire de manière à engendrer par réactions nucléaires, en ce point et sur une profondeur prédéterminée, des isotopes radioactifs, localisables par un détecteur de rayons gamma, au sein du matériau constitutif prédéterminé (14). Cette inscription est invisible.
