Abstract

This paper describes an acoustical method for detecting small scattering sources in thin polymer films with high sensitivity. The technique monitors the acoustic resonance occurring between water, the film and a metallic plate, and an accurate measurement of the ultrasonic attenuation in the film at the resonant frequency is made. Micro-bubbles in the film cause the ultrasonic attenuation in the film to increase.
