Abstract
An improved ultrasonic transducer in which signals from portions of the transducer located a distance apart from each other are compensated for the cancellation affects due to a reflected energy striking one part before the other by use of switching circuits which pass either in-phase or out-of-phase components from the portions of the transducer to a summing circuit in such a manner that the summed output is improved.
