ABSTRACT:
A method is provided for manufacturing crossing/intersecting transducer arrays including first and second ultrasonic transducer arrays which intersect centrally of one another. Each transducer operates independently without any decrease in acoustic performance. The first and second arrays have their own independent signal electrodes, respectively disposed on the front and rear surfaces of the device. Because the arrays are built on a unique piezoelectric member, a portion of signal electrode of each array is adapted to be connected to ground in a manner permitting proper operation of the entire array. A method of forming matching layer sets incorporating electrical interconnections is also provided.
