Résumé

This paper presents a NDT method by infrared thermography with a microwave excitation system applied to the detection of metallic parts: a metal ring behind a wooden plate of 1cm thick, a reinforcement bar in front of a concrete wall and the detection of reinforcement bars equally spaced in a concrete slab of 6.5 cm thick. The excitation device is based on a magnetron associated with a horn pyramidal antenna. A contrast algorithm applied to the sequences of thermograms highlights metal ring or bars location.
