SYSTEM FOR IDENTIFYING OBJECTS

摘要

The invention concerns a system for identifying an object comprising an identifying support related to the object or forming part thereof, and a head for scanning said number. It is useful, for example, for identifying nuclear fuel elements before and after irradiation. The invention is characterised in that the support (1) has at least a planar surface (6) wherein are perforated several marks (12) aligned uniformly along at least a circular line, each mark having one among a plurality of discrete depths based on the identification of said objects. The scanning head (3) comprises means (13) to be located opposite said planar surface (6), means (9) for scanning said surface (6) and means (8) for measuring the depth of said marks (12).
