Abstract :
The bond integrity between optically bonded fused quartz blocks has been evaluated using ultrasonic waves in the frequency range from 200 MHz to 800 MHz. The ultrasonic waves were produced by thin-film zinc oxide (ZnO) transducers. By excitation of the thin film ZnO transducers on glass blocks of two different thicknesses and optically bonding their free surfaces opposite the transducers, the properties of the bonded area can be evaluated using transmission and reflection loss measurements. The measurements were made using pulse excitation and detection, and spectrum analyzer measurements
