1. A device for non-destructive testing of a mechanical part made of a polycrystalline material, comprising:
an ultrasonic probe including a two-dimensional array of transducers capable of emitting and receiving signals at different excitation angles, and
a processor configured to
test the transducers in emission and in reception,
process the signals received by the transducers so as to express the signals received by the transducers in two planes of plane-waves constructed from emission and reception wave vectors of the probe by summation and difference of the wave vectors associated respectively with the plane-waves emitted and received by the probe, and
deduce information representative of a three-dimensional orientation of a fiber structure of the mechanical part.
