TLDR
In this article, Berek and Ehringhaus rotary compensators are analyzed within the framework of classical electromagnetic theory, and exact solutions for the phase difference and amplitude ratio of the transmitted light can be determined.Abstract:
The theory conventionally used to describe the operation of Berek and Ehringhaus rotary compensators is based on geometrical optics and, hence, is not exact. When rotary compensators are analyzed within the framework of classical electromagnetic theory, exact solutions for the phase difference and amplitude ratio of the transmitted light can be determined. The approximate and exact solutions differ in some interesting ways which become of substantial importance in the examination of monochromatic plane waves of light. In particular, the discrepancies between exact and approximate solutions become more pronounced at high angles of incidence. Exact theory predicts the possibility of using a high-refractive index isotropic plate for measuring small phase differences at relatively long wavelengths.read more

Formulas for Using Wave Plates in Ellipsometry

TL;DR: Formulas are presented for the use of optical compensators in ellipsometers that can be used, without modification, when the compensator is not an exact quarter-wave plate, when multiple internal reflections are present, and when the compensate is absorbing.

TL;DR: The complete polarization state generator (PSG) as mentioned in this paper consists of one rotatable polarizer and one variable retarder with a quarter-wave plate, which is employed in the quantitative orientationindependent differential polarization microscope, which uses polarized light states with the same ellipticity and different orientation angles.

Transmission ellipsometry on transparent unbacked or embedded thin films with application to soap films in air
TL;DR: The ratio rho(t) = T(p)/T(s) of the complex amplitude transmission coefficients for the p and s polarizations of a transparent unbacked or embedded thin film is examined as a function of the film thickness-to-wavelength ratio d/lambda and the angle of incidence Phi for a given film refractive index N.
