| Abstract |
The electroacoustic measurement model is an explicit model of an entire ultrasonic
measurement system, including the pulser/receiver, cabling, and transducers. A summary is given of
the measurement procedures needed for characterizing all the system elements contained in this
measurement model, including a description of a new pulse-echo method for obtaining the
sensitivity and impedance of an ultrasonic transducer. It is demonstrated that these models and
measurement procedures can be combined to accurately simulate the measured voltage of a pulseecho
immersion system. |
