Modern Transducers, Theory and Practice
After a survey of the historical development of sonar-transducers an account is given of the design and construction of piezoelectric piston elements, to be mounted in transducer arrays for active sonars. Flextensional transducers are mentioned briefly, and also bimorphs and free flooded rings for deep water operation. Design considerations for hydrophones are discussed, paying attention to multimode hydrophones for directional sensitivity. For calibration of large transducers the near field technique is recommended.
