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