Abstract
A transducer array and excitation circuitry for producing ultrasonic waves in a controlled pattern and for causing the waves to be scanned along the array. The array comprises a plurality of transducer elements coupled to each other in such a way as to produce a desired wave pattern when selected elements are activated. The array may be constructed from plural transducer elements or from a single plate of transducer material comprising a plurality of elements that can be individually activated, the plural elements being intercoupled to produce the desired wave pattern. The arrangement is such that a minimum number of electrical connections to the transducer elements are required to create the desired wave pattern and to scan that pattern across the face of the array.
