Abstract: | This is a study of the effect of the ellipticity of the polarization of radiation at the inlet of the shaping polarizer in
the probe channel of a Mueller polarimeter operating with three linear probe polarizations on the accuracy with which the
incomplete Mueller matrix is determined (without a fourth beam). It is shown that the appearance of and variations in the
ellipticity cause a change in the conditions for optimization of the set of polarizations of the probe radiation from the
standpoint of minimizing the measurement error. In the case of linear polarization (zero ellipticity), the measurement error
is the same as the error when four probe polarizations are used. This allows measurement of the complete Mueller matrix and
makes this version of the polarimeter especially promising, because in the input channel of the polarimeter, a single polarizing
element, i.e., a linear polarizer with a controllable azimuthal orientation, can be used as the polarization transducer.
