Transducer Reception Process

From results obtained in Chaps. 8 and 10, we 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 model the reception of those scattered waves at the face of a receiving transducer. In the paraxial approximation, the reception process like the transmission process can be characterized by a diffraction correction term. This diffraction correction term and an additional factor due to averaging the waves over the receiver face constitute the reception term in an LTI model of an ultrasonic system.
