Highly Efficient Transducer Arrays Useful in Nondestructive Testing Applications,

Abstract

The development of two types of transducer arrays for use in a synthetic aperture digital acoustic imaging system is described in this paper. One type of array using narrow slotted piezoelectric elements is most suitable when the acoustic impedance of the load medium is low with respect to that of the piezoelectric ceramic. A second type of array of monolithic construction is useful when the acoustic impedance of the load medium is similar to that of the ceramic, as would be useful for a contracting transducer for nondestructive testing of metals and ceramics.
