中文摘要
最近发展的全息产生相干超声的光学方法将用于产生连续可调谐的极高频率的相干声波。这些特点,再加上无需机械接触的光学注入声学探针的能力,使得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.
