METHOD FOR CHARACTERISING AN OBJECT COMPRISING, AT LEAST LOCALLY, A PLANE OF SYMMETRY

摘要

The invention concerns a method for characterising an object (300) comprising, at least locally, a plane of symmetry (PI), the method comprising at least one observation of ultrasound emitted by said object, each observation being carried out on an axis (d) perpendicular to the plane of symmetry (PI), each observation following an ultrasound emission generated respectively according to said axis (d) and meeting the object (300) along said axis (d) with an angle of incidence (-1) different from the normal, the ultrasound meeting the object (300) in such a way as to follow a path symmetrical to the plane of symmetry (PI).
