Transducer Arrays Suitable for Acoustic Imaging,

Abstract

Progress on the development of piezoelectric transducer arrays for use in electronically focused acoustic imaging systems is reported. Design techniques and experimental results are described for two types of transducer arrays, one utilizing individual slotted array elements, and the other, array elements constructed by depositing electrodes on a monolithic slab of piezoelectric ceramic. Development of lossy, high impedance tungsten-epoxy matched backing material, necessary for broad bandwidth transducer arrays, is also described. (Author)
