Description

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

Using a Large Aperture, Phase Insensitive Array Transducer to Improve Ultrasonic Detection of Disbonds at a Rough Interface
