A measurement of ultrasonic attenuation in bonding layer of an ultrasonic delay line is proposed. The method is based on the. fact that the reflection coefficient R and transmission one T of an ultrasonic cave at a bonding layer depend on the attenuation in the layer. Thus, the ultrasonic attenuation in a bonding layer can be determined by measuring R and T. The coefficients of R and T are measured through the use of light diffraction phenomenon due to acoustic waves. The results of the measurement of attenuation constants of transverse waves are reported for several bonding materials.
