Abstract :
In the present paper, heat wave (LIMM) and pressure pulse measurements are reported of the polarization and electric field distribution in nonuniformly electron-beam poled PVDF. In order to obtain the spatial distributions from the LIMM spectra, the regularization technique is applied to the deconvolution. In this connection nonlinear grid distributions are discussed. The polarization profiles obtained by the two methods are compared over the whole thickness range, and a satisfactory agreement is found
