Query: Maximum-likelihood estimation prevents unphysical Mueller matrices   We show that the method of maximum-likelihood estimation, recently introduced
in the context of quantum process tomography, can be applied to the
determination of Mueller matrices characterizing the polarization properties of
classical optical systems. Contrary to linear reconstruction algorithms, the
proposed method yields physically acceptable Mueller matrices even in presence
of uncontrolled experimental errors. We illustrate the method on the case of an
unphysical measured Mueller matrix taken from the literature.
