Abstract
The FLIMM (Focused Laser Intensity Modulation Method) allows the experimental determination of space charge or polarization profiles in thin (<100 μm) polymers by detection of a periodic thermally induced current. In this paper, we propose to show that a bidimensional scanning of the beam and a three-dimensional modelling of the temperature can lead to a 3D spatial determination of the space charge profile. Some results on PE test samples are discussed.
