Abstract :
The regularization technique is applied for the first time to the deconvolution of thermal pulse data in order to obtain the spatial distributions of polarization and space charge in thin electret films. The temperature profile used is the solution of the heat conduction equation for a substrate-mounted sample with the heat transfer on the rear side of the sample considered. Substrate mounting prevents spurious high frequency oscillations, but requires careful consideration of the heat transfer in order to determine the spatial distribution over the whole thickness. We also discuss the influence of the metallic front electrode on the temperature profile and on the spatial distributions
