Abstract

Complex refractive index of strongly depolarizing starch acetate is investigated as a function of bulk package density, which is compulsory parameter in analysis of light scattering from nanoscale starch acetate pigments and fillers.
The measurements were made using a laser-goniometer and spectrophotometer to gain data for refractive index analysis according to the Brewster’s law and Fresnel equations.
The real part of refractive index was verified by microscopic immersion method.
