Abstract: The invention relates to a thermographic system comprising infrared imaging means, a radiation source and a duct (18) for guiding the radiation in a longitudinal direction (L) to an outlet of the duct (18) located at a free edge (28) thereof, characterized in that the free edge (28) of the duct (18) is deformable along the longitudinal axis (L) in a first direction (L1) oriented from the outlet of the duct (18) towards the imaging means (12) and in that it comprises means for returning the free edge to its initial shape and means for holding said free edge of the duct (18) in a deformed state.

Abstract: A method of non-destructive testing of an aeronautical component, including a righting processing including Generation of a median surface of the component extracted from a tomographic volume, the median surface dividing the component into two parts, Determination of a field of normal vectors normal to the median surface, Flattening of the median surface to form a flattened median surface in a plane, Reconstruction of a righted volume containing the component righted about the flattened median surface, the reconstruction being performed by mapping between voxels of the righted volume along directions orthogonal to the flattened median surface and between voxels of the volume along the normal vectors of the median surface which are associated with these respective orthogonal directions, Analysis of the righted volume thus obtained so as to identify the anomalies of the component.

Abstract: A phantom for use in quality control of tomographic images, the phantom including a cylindrical plate made of a uniform material having a density d1, with two cylinders being inserted in the plate, the cylinders being made out of uniform materials having different densities d2, d3, the density of one of the cylinders being greater than the density d1 of the plate, and the density of the other cylinder being less than the density d1 of the plate, and including a first series of pairs of holes of different diameters drilled in the plate, the axes of the holes of the first series being oriented axially relative to an axis of revolution of the plate, and the holes in a given pair being spaced apart from each other by a distance equal to their diameter.
