The Application of Polarization Modulation Method to Investigate the Optical Homogeneity of Polymer Films

Abstract

A new use of commercial CD spectrometers is proposed for investigating the optical homogeneity of polymer films, in other words, for determining whether polymer films have uniform one layer structure or whether they are inhomogeneous with a multi-layer structure. The Mueller matrix approach was intensively used for the theoretical back-up of this method and for analyzing the data obtained on Congored dyed polyvinyl alcohol (PVA) films.
