Abstract:
A method of measuring both the polarized spectral response and the nonpolarized spectral response of a sample comprising the steps of:illuminating the sample with polarized light; measuring the nonpolarized spectral response of the sample at a plurality of discrete nonpolarized wavelengths; measuring the polarized spectral response of the sample at a plurality of discrete polarized wavelengths, the discrete polarized wavelengths being a nonidentical subset of the discrete nonpolarized wavelengths; and calculating the polarized spectral response at each discrete nonpolarized wavelength that is not also a discrete polarized wavelength, the calculating step being a function of the nonpolarized spectral response at the wavelength and the relationship of the polarized responses and the nonpolarized responses at other wavelengths.
