The optical property of biological skin is reconstructed from published experimental absorption data. A smooth chart of all relevant data is formed by splicing, interpolation and extrapolation methods. The regularized set of absorption data is transformed through Kramers-Krönig relations to yield a set of theoretical index of refraction for biological skin. The well known absorption characteristics of pure liquid water provide supplemental information for missing data. The Kramers-Krönig transformation is numerically realized through Discrete Fourier Transforms and enables the use of the Fast Fourier Transform (FFT) algorithm. A unique implementation of Richardson's extrapolation method reduced multivalued point sets containing experimental absorption data. Extrapolation techniques also aided in covering unavoidable gaps in experimental data.
