Abstract

Acoustography is being developed as an alternative to conventional point-by-point ultrasonic scanning commonly employed for composite inspection. In acoustography, an area detector is used to produce full-field images of the test component in near real time, which makes the method suitable for providing rapid ultrasonic inspection of composites. Although the possibility of using acoustography to inspect composites has recently been demonstrated, a side-by-side comparison of acoustography with conventional ultrasonic scanning has not been made. In this work we will report on studies conducted toward establishing a direct comparison between acoustography and conventional ultrasonic scanning.
