Abstract
An acoustic inspection device and an associated method for inspecting a component are provided. The acoustic inspection device is portable and includes an acoustic transmitter and receiver that may be placed on opposite sides of an inspection region on the surface of the component. The acoustic transmitter has an array of acoustic transducers for generating an acoustic wave that travels along a surface of the component and the acoustic receiver has an array of acoustic transducers for receiving that acoustic wave. A controller determines at least one surface characteristic of the component from the measured acoustic wave, such as its crystalline structure or grain size.
