Summary:The article presents the results of experimental determination of the structure of surface vibrations of a two-dimensional phased ultrasound probe using transient acoustic holography in the frequency range from 0.1 to 10 MHz. It is shown that this method makes it possible to detect individual elements operating with parameter deviations from the nominal values, including inactive ones. A comparison is made with the results of echo pulse measurements for each element, as well as measurements of the electric capacitance of the elements.
