Abstract
From the results obtained in Chaps. 8 and 10, we now know how to model the incident sound beam produced by a transducer and the waves scattered from a flaw due to such an incident wave field. In this Chapter, we will model the reception of those scattered waves at the face of a receiving transducer. It will be shown that in the paraxial approximation the reception process, like the transmission process, can be characterized by plane wave propagation terms and a diffraction correction term. This diffraction correction term and an additional factor due to averaging the waves over the receiver face will constitute the reception term that appears in a Thompson-Gray measurement model of an ultrasonic system.
