Abstract: Registration of ultrasound excited by a laser in a metal plate with a broad-band EMA receiver is studied experimentally. The results can be used to create a non-contact methods of ultrasonic testing of sheet metal products.

Keywords: laser excitation, ultrasonic Lamb waves, EMA-wideband receiver, range, ferromagnetic metal.
