Abstract
We present a setup established to measure the light polarization state based on the general concept of Stokes polarimeter. This setup consists of two liquid crystal modulators (LCMs), linear analyzer and CCD camera connected to PC computer. Using this polarimeter all two-dimensional distributions of main polarized light parameters can be measured. The measurement process consists of six fast intensity distributions measurements. In addition to the setup description we discuss also the ways of the angular justification of both LCMs elements as well as the proper selection of the LCMs' input voltages. The results of the measurement of some exemplary uniform and non-uniform polarized light distributions are presented.
