Abstract

The determination of the actual vibration distribution of an ultrasonic transducer radiating into a liquid is identified as one of the major unresolved questions of precision ultrasonic science. Direct measurement of the surface vibration distribution using optical interferometry is not possible due to the piezo-optic effects of the radiating ultrasonic beam on the liquid through which the optical interferometer beam must travel. An analysis is presented which relates the actual vibration distribution to that which would appear to be measured. The possibility of inverting this process to retrieve the original distribution is identified.
