中文摘要
翻译
最近发展起来的全息产生相干超声波的光学方法将被用来产生频率极高的连续可调的相干声波。这些特点,再加上光学注入声学探头而不需要机械接触的能力,使所提出的技术非常适合于材料的非破坏性评估。
英文摘要
Recently developed optical methods of holographically generating coherent ultrasonics will be employed to produce coherent sound waves with extremely high frequencies that are continuously tunable. These features, coupled with the ability to optically inject acoustic probes without mechanical contact, makes the proposed technique well suited for the non-destructive evaluation of materials.
