Implementation: Presentation Status and Future Directions
The previous papers present a number of techniques for quantitatively identifying the size, shape and orientation of defects in solid parts from the ultrasonic scattering information available at a single surface. This paper summarizes these results and discusses their interrelationships. A "decision tree" "is presented which identifies the options that should be selected in various situations. Areas where future or in-progress work. can be expected to have an impact on such procedures will be identified.
