Acoustography provides an alternative to the conventional point-by-point ultrasonic scanning approach commonly used for composite inspection. In acoustography, an area detector (sonoplate) is employed for near real-time imaging of composites. In this paper, we report on the application of acoustography for ultrasonic inspection of tight-radii in composite components/specimens, where conventional point-by- point ultrasonic scanning may not be practical and/or cost- effective.
