Complete ultrasonic transducer characterization and its use for models and measurements.

摘要: Transmitting and receiving properties of ultrasonic piezoelectric crystal transducers that directly affect the measured output voltage in an measurement system are described. These transducer transducer's electrical impedance sensitivity, radiation impedance, effective parameters (effective radius focal length). It is shown all these can be obtained with a series calibration measurements, most them purely nature. This measurements described, including newly developed method makes determination sensitivity simpler than previous methods. demonstrated by combining knowledge pulser/receiver cabling acoustic/elastic processes present system, it possible to accurately simulate system.
