    Transducers for use in a pulsed digital reflection acoustic microscope in the frequency range 25-100 MHz are considered. The concept of the MTF to the characterisation of high frequency ultrasonic transducers of the type used in pulsed acoustic microscopes is applied taking into account the additional complication of the ultrasonic imaging and an overall characterisation procedure has been develop...

    The computer-aided design approach to ultrasound transducers has proved to be extremely useful. It has improved one's understanding of the behaviour of these devices as various design parameters are varied and it enables one to experiment with a wide range of approaches to a particular design problem without having to resort to manufacturing devices at each stage of the iteration. Very accurate ma... View full abstract»

    The theoretical characterisation, design and evaluation of ultrasonic transducer systems have formed a major activity at Strathclyde University in 1980s. Over this period, substantial government and industrial funding has been awarded to a specialist ultrasonics research group for the study of piezoceramic transducer signal generation and analysis when applied to sonar, non-destructive testing (ND...

    A brief description of the theoretical approach is presented, including a discussion of the plane and edge wave components present within the resultant waveforms. The predictions of theory are then compared to experimental results for two cases; generation by a wide bandwidth piezoelectric longitudinal contact transducer, and the source created by pulsed laser irradiation of a solid surface View full abstract»

    The underwater imaging systems developed at Portsmouth use linear arrays of PZT transducers for transmit and receive. The authors describe the design and construction of a pair of parallel arrays of 32 transducers for operation at about 2 MHz. The technique used to enable the satisfactory fabrication of a small scale array, within a development laboratory, are included. Preliminary results of the ... View full abstract»

    An ultrasonic array structure has been developed for use as part of a condition monitoring system. The structure consists of a monolithic plate of a piezoelectric material bonded to a standard printed circuit board whose copper tracks define the array element pattern. This configuration places few restrictions on the piezoelectric material and its dimensions and on element geometry, and requires m... View full abstract»
