Abstract
The temperature stability of ultrasound transducers and arrays has for many years been an important, but background criterion for the transducer design
engineer. However, in many applications such devices are increasingly required to operate at significantly elevated temperatures, either through ambient conditions or as a result of internal temperature increases during high power
operation. Relevant applications include high temperature non-destructive evaluation (NDE), industrial process control, and underwater sonar. When it is considered that many modern transducer devices comprise a controlled,
multi-phase mixture of active and passive components, optimized for efficiency, bandwidth, and beam pattern, the issue of temperature stability is by no means trivial.
