Abstract
A Barker-coded multiple layer piezopolymer transducer design is described. The design is intended to improve the transmitting sensitivity of a PVDF transducer while retaining PVDF material's wide bandwidth properties. Computer simulations of the coded multilayered PVDF transducer were carried out and several prototypes of the transducers were built and tested. The results of comparisons between the measurements and theoretical predictions are presented. Advantages and disadvantages of the coded multilayer approach to bandwidth enhancement of ultrasound transducer are also discussed. Barker-coded transducers hold promise to emerge as a new class of ultrasound imaging transducers having a sensitivity on par with that offered by presently used PZT or composite transducers but with significantly wider bandwidth.
