Boev S.G., Kuz'min A.N., Lopatkin S.A., Paderin V.A. «Probing the distribution of bulk charge and polarization in solid dielectrics by acoustic pressure pulses» Приборы и техника эксперимента, 36, № 4, с. 187-196 (1993)

A brief analysis is given for the results of physical description of the method; its potentialities and conditions of implementation for probing the distribution of bulk charge’s electric field intensity and polarization across a plane-parallel sample are considered. A device implementing the method on the basis of the inverse piezoelectric effect is described. This device makes it possible to probe the samples with frequencies of hundreds and thousands Hz with a field sensitivity threshold ≤10² v/cm and a resolution ≤20 μm. The application of the method is illustrated by experimental results.
