本文综述了空气耦合超声在工业材料表征和无损检测中的应用。本文简要地讨论了空气耦合转导和电子学方面的发展，尽管这里的重点是表征和检查方法，以及克服使用像空气这样微弱的声音耦合介质所固有的局限性。介绍了兰姆波在板材表征中的作用，包括使用空气耦合声束来测量材料的弹性和/或粘弹性。空气耦合声探测，当采用其他方法产生高振幅声束也进行了审查。应用于土木工程，声学层析成像，以及纸张和木材的特性处理在这里。简要概述了空气耦合声阵列的发展以及空气耦合方法在非线性超声中的应用。特别是，伯纳德·霍斯滕教授和他在波尔多的合作者的工作被仔细检查。(C) 2014 Elsevier B.V.版权所有
This article presents a review of air-coupled ultrasonics employed in the characterization or nondestructive inspection of industrial materials. Developments in air-coupled transduction and electronics are briefly treated, although the emphasis here is on methods of characterization and inspection, and in overcoming limitations-inherent in the use of such a tenuous sound coupling medium as air. The role of Lamb waves in plate characterization is covered, including the use of air-coupled acoustic beams to measure the elastic and/or viscoelastic properties of a material. Air-coupled acoustic detection, when other methods are employed to generate high-amplitude sound beams is also reviewed. Applications to civil engineering, acoustic tomography, and the characterization of both paper and wood are dealt with here. A brief summary of developments in air-coupled acoustic arrays and the application of air-coupled methods in nonlinear ultrasonics complete the review. In particular, the work of Professor Bernard Hosten and his collaborators at Bordeaux is carefully examined. (C) 2014 Elsevier B.V. All rights reserved.
