The Chief Scientist in this specialty area of transducers and arrays is Dr. John L. Butler. He has over 35 years experience in the design and analysis of transducer elements and arrays. He holds seventeen patents, has published over 25 papers on electro-acoustic transducers and was elected Fellow of the Acoustical Society of America in 1977. His experience includes the design of Flextensional, Tonpilz piston type, Ring, Cylindrical, Hybrid (piezoelectric/magnetostrictive), Bender and other underwater sound projectors and various hydrophones. His experience includes the use of piezoelectric, magnetostrictive (Terfenol-D and Metglass) PMN-PT, PVDF and 31 composite transduction materials. His most recent publication is "A tri-modal directional transducer," (with A.L. Butler and J.A. Rice) J. Acoust. Soc. Am., 115, 1-8 (1995).

Image Acoustics, Inc. uses Finite Element Analysis and a battery of transducer and array computer programs to perform efficient and effective design and analysis. Many of these programs were developed and coded at Image Acoustics, Inc. and are available for commercial use. For information on Image software see "SOFTWARE" on the Image homepage.
