Abstract

A new method for generating three dimensional images of flaws in elastic solids from backscattered data at a finite number of look angles (usually 2 to 3) is presented. The procedure is based on the physical elastodynamics aporoximation which leads to a relationship between the backscattered ramp response to an incident ultrasonic ramp pulse and the area of cross section of the object along the “line of sight.”
