Abstract
Attenuated total reflection leaky-mode spectroscopy is used for a ther mo-optical investigation of a clamped film of the ferroelectric vinyli dene fluoride-trifluoroethylene copolymer. A hysteresis loop for the o ptical parameters refractive index and film thickness is found for a f ull temperature cycle between 25-degrees-C and 60-degrees-C. In the vi cinity of the ferroelectric/paraelectric phase transition increased op tical losses are found.
