An instrumentation scheme is presented which provides a calibrated field intensity equivalent plot using common laboratory equipment. The parameter that is measured gives a direct indication of the merit of an ultrasonic transducer for a given application in terms of its beam shape. The composite output of the system yields a three-dimensional representation of the intensity equivalent parameter as a function of a two-dimensional spatial field. Several applications of the resulting instrumentation are given including the effects of crystal window flatness and acoustic lensing.
