【 摘 要 】

We present two laser-based measurement techniques for investigating the refraction of polymer solutions, thin polymer films and bulk samples. Our results confirm the fact that the refractive indices of polymer films differ from those of bulk polymer samples and polymer solutions. However, the analysis of the dispersion yields similar results for all states of the polymer.
