Abstract : An acoustic transducer is constructed as a stacked configuration of multilayer transducer elements separated from one another by an electrical insulating material. Each multilayer transducer element has a layer of acoustically transparent electroacoustic transducer material having opposing planar surfaces with electrically conductive material deposited thereon. For each multilayer transducer element, the electrically conductive material is formed into parallel strips electrically isolated from one another on at least one of each element's opposing planar surfaces. The parallel strips associated with each multilayer transducer element have a unique angular orientation.
