Acoustography provides an alternative to the conventional point-by-point scanning employed for ultrasonic NDE of composites. In acoustography, an acousto-optic area detector is used to provide near real-time ultrasonic imaging of composites. This paper reports on a number of recent improvements that have been made in acoustography, including acoustic detection sensitivity, dynamic range and image quality. The potential of this NDE approach for providing efficient, cost-effective and practical inspection of composite components is presented.
