Abstract
We describe a numerical method for obtaining a nondepolarizing estimate from an experimental Mueller matrix, a necessary preliminary step in determining the Jones matrix and the polarization properties of the sample under study. The proposed method, being a variant of the general virtual experiment approach, is based on minimizing the least squares distance between the light intensities virtually generated by the effectively measured Mueller matrix of the sample and by its nondepolarizing estimate, while taking into account the exact phenomenological description of the polarimetric instrument used. It can be applied to complete, as well as to partial (12-element) experimental Mueller matrices. The application of the method is illustrated on experimental examples and its performance is compared to that of alternative approaches.
