Abstract
Vinylidenefluoride-trifluorethylene copolymer films were polarized under different conditions and then investigated with the laser intensity modulation method (LIMM) and the laser induced thermal pulse technique, (LITP). For thick films with thick electrodes the results derived from LIMM and LITP experiments are identical. For thin films experimental and methodical constraints influence the applicability and resolution achieved with LITP
