Abstract:

Subject of study. Efficiency of an absorber of s-polarized transverse ultrasonic waves is considered. Aim of study. Determination of the structure of the acoustic field in acousto-optical devices. Development of a methodology for assessing the efficiency and quality of ultrasonic absorbers of acousto-optical devices, based on the analysis of echo-pulse ultrasonic signals. Method. Using surface scattering to determine the degree of absorption/reflection of ultrasound. Main results. Developed method for determining the quality of the applied absorbent coating. Practical significance. The method complements a set of previously developed methods for determining the structure of an acoustic Bragg diffraction grating, which determines the characteristics of acousto-optical devices.

Keywords:
