Characterization Of Heterogeneous Media With Multicomponent Laser Ultrasonics, Thomas E. Blum
Characterization Of Heterogeneous Media With Multicomponent Laser Ultrasonics, Thomas E. Blum
Boise State University Theses and Dissertations
Wave propagation in scattering media is a complicated topic, but scattered elastic waves carry important information about the internal structure of the medium. It is a current topic of research and for the foreseeable future. Advances in theory and applications described in this manuscript benefit from new ways to collect more densely sampled, multicomponent, true-amplitude data.
Thus far, most fracture characterization experiments in the laboratory involve contacting transducers as elastic wave sources and receivers. Similarly, rock properties such as anisotropy and attenuation are also measured with contacting techniques. These type of measurements are well-suited for time-of-flight measurements, but for scattering …
