optical-acoustic diagnostics, acoustic spectroscopy, electron speckle interferometry

A method of synchronous removal of vibroacoustic and speckle interferometric information for the diagnosis of defects is proposed on the example of the diagnosis of defects in fixing the boundary of the test plate in the form of a cardiode. The method makes it possible to judge not only the presence of defects by changing the spectral composition of its vibration and sound fields, but also makes it possible to determine the location of the defect by distortion of the speckle interferogram of the field of plate surface changes.
