Abstract:
The participants of the optical-acoustical diagnosing of wedge-form defects in solid state body is investigated. It is shown that due to interferential effects scattering efficiency varies nonlinearly with an increase of defect size, reaching a maximum at a certain amount of it. It has been established that the study of the pulse energy characteristics of ultrasonic scattering radiation on the wedge-form defects, at the approximation different from Rayleigh allows determining the size of the defect, angle at the vertex of the wedge, angle of the inclination and location.
