Description
Summary:The objective of this research has been to apply optical holographic techniques coupled with electronic signal and image processing to provide quantitative, full field measurements of acoustic wave disturbances. This program has sought to establish the limits of sensitivity with which surface acoustic waves might be measured and mapped. In addition, an effort to extend heterodyne holographic measurements to the examination of acoustic energy flow in optically transparent bulk materials has begun.
