A method (100) for determining incipient mechanical failure of an object includes insonifying the object with ultrasonic energy at a selected fundamental frequency. Amplitude data is acquired (108) from the insonified object at the fundamental frequency and at a second harmonic of the fundamental frequency, and a non- linear acoustic image is generated (110) from the amplitude data at the fundamental frequency and the second harmonic frequency.
Méthode (100) pour déterminer les débuts de panne mécanique d'un objet, qui comprend l'exposition de l'objet à une onde acoustique d'énergie ultrasonique à une fréquence fondamentale choisie. Les données d'amplitude sont acquises (108) de l'objet exposé aux ultrasons à la fréquence fondamentale et à une seconde fréquence fondamentale harmonique; une image acoustique non linéaire est générée (110) à partir des données d'amplitude à la fréquence fondamentale et à la seconde fréquence harmonique.
