Applications of very high frequency acoustical imaging to the local characterization of materials
Published online by Cambridge University Press: 25 October 2002
Abstract
1 GHz very high frequency acoustical imaging displays a micronic resolution. Owing to its nature of sub-surface imaging, it is well adapted to the characterization of porosity. Used as a means for quantitative measurements through acoustic signature processing, it provides sufficiently localized information to characterize the elastic properties proper to each component of a SiC/SiC minicomposite, the fiber and the matrix.
