ABSTRACT:
A piezoelectric transducer array comprises a plurality of piezoelectric transducer means arranged in an array. A common electrode is provided among at least a plurality of the piezoelectric transducer means. A plurality of discrete signal electrodes is operatively associated with each transducer means. The number of signal electrodes for each transducer means is the same. The surface areas of the signal electrodes for each transducer means are adapted and arranged for generating a signal unique to each transducer means. Corresponding ones of the signal electrodes of each plurality of signal electrodes are connected together with a common conductor to form a single electrical terminal. The total number of resulting electrical terminals is the same as the number of signal electrodes for each transducer means.
