Abstract: As insulators are stressed with a strong electric field, they store electric charges that can be represented as space charge distributions. We propose a simple equivalent model of these distributions in order to characterize the internal residual field in a thin polymeric insulator using a frequency-based technique called focused laser intensity modulation method (FLIMM). This approach shows its ability to follow simple evolutions resulting for example from an increasing of stressing field or of the poling duration time, avoiding in a first approximation the use of complex mathematical algorithms.
