Abstract:

In this paper we discuss an original technique for eliminating the contribution of a partially—polarized background component of an input optical field to the components of the Stokes vector in the study of the polarization characteristics of different natural objects. This technique is based not only on the polarization modulation of a light field in a recording channel but also on modulation of the intensity of a light field in a sounding channel of a polarimeter. This technique can be implemented in the optical scheme of any modulation polarimeter. It is shown that in so doing, no information about the absolute values of the initial phase and frequency of the amplitude modulation is needed.
