Abstract
The scanning of a surface of a part is carried out by a means of imparting heat to at least one heating zone at the surface of the part. This occurs by relative displacement of the part and of the means of imparting heat. A detector is used to sense the flux radiated by the surface of the part in a detection zone displaced synchronously with the movement of the heating zone. The detector delivers, for each of the positions of a set of successive positions of the detection zone, a signal representative of the flux radiated. The scanning of the surface of the part is carried out along a determined path, in a first direction, then in a second opposite direction. For each of the successive positions of the detection zone, a differential signal is formulated.
