Abstract

L'invention concerne un procédé d'implantation d'un dispositif de sécurité dans un document de sécurité, lequel comporte un film polymère cible (1). Le procédé consiste à irradier au laser un film support polymère (2) dopé avec des molécules dopantes (3), selon un schéma de sécurité prédéfini, en appliquant une intensité suffisante pour introduire les molécules dopantes (13) dans le film polymère cible (1), mais inférieure à celle provoquant l'ablation d'un film support polymère (12).
