摘要: The determination of whether two surfaces are bonded or unbonded is commonly evaluated using conventional ultrasonic transducers which phase sensitive and are, therefore, very to surface irregularities. More often than not, interfaces not flat, but irregular uneven. Thus, another technique required test those interfaces.
