| Zusammenfassung: | The invention relates to a method for indirectly measuring ultrasonic transducer frequency response characteristics. When frequency response characteristics of an ultrasonic transducer are measured, firstly, a precision impedance analyzer is used for measuring the electrical impedance frequency spectrum of the ultrasonic transducer, the frequency response curve of the transducer is obtained by carrying out calculation according to the electrical impedance frequency spectrum, and therefore the center frequency, the bandwidth and other performance parameters of the transducer are obtained. The method simply needs to measure the electrical impedance frequency spectrum of the ultrasonic transducer, and the impedance characteristic and the frequency response characteristic of the ultrasonic transducer can be obtained simultaneously, and the efficiency of measuring the ultrasonic transducer frequency response characteristics can be improved. The invention provides a novel method for obtaining the frequency response |
