N2 - 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.
