9. Defect Characterization: Fundamentals
I am going to report briefly on the Acoustical Imaging and Holography Conference that was concluded yesterday in Chicago. These conferences were started in 1967, and are concerned primarily with ultrasonics and visualization techniques as applied to medicine, nondestructive evaluation, sonar, seismic analysis and acoustic microscopy.
