Abstract
In this paper, the acoustic microscope with a linear ultrasonic array and a cylindrical lens has been proposed in order to carry out quantitative characterization of layered regions of the sample under research. The determination method based on recording the microscope array spatio-temporal signal of the layer thickness and velocities of the longitudinal and transverse waves in the layer material has been developed. By using a test sample, it was shown that the error of measurement is about 1 % for both the thickness and the velocity of the longitudinal wave, and it is 3 % for the velocity of the transverse wave.
