METHOD FOR AUTOMATICALLY IDENTIFYING A MATERIAL OR AN OBJECT

摘要

The invention relates to a method for identifying and/or authenticating a material or an object, especially for the purpose of sorting materials or objects, characterized in that it comprises: an excitation step comprising the application of a plurality of excitation vectors to a material or an object; a detection step in which the responses of the materials or objects subjected to said excitation vectors are detected; and a step of determining at least one item of information relating to said material or object on the basis of said responses obtained and of a pre-established look-up table. These steps will have been preceded by the incorporation, into or on the surface of the materials or objects, of at least one substance selected so as to react to at least one excitation vector and by the generation of a look-up table consisting of a set of one-to-one relationships between a combination of responses and an item of information relating to said material.
