Abstract:
Full Poincaré beams have been recently applied in polarimetry for determining the Mueller matrix of homogeneus samples. Such matrix can be obtained from the measured Stokes parameters at four selected points across the transverse section of a full Poincaé beam before and after the sample. Since the transverse section of a full Poincaré beam contains all the possible states of polarization, the possibility of changing the input polarization state on selecting different points could be exploited to get a better accuracy in the determination of the Mueller matrix. To this aim, a polarization state analyzer with a CCD camera can be used to obtain maps of the Stokes parameters across the transverse section of input and output beams. The analysis of the obtained polarization maps can lead to the determination of the Mueller matrix with reduced uncertainties. Several simulations are presented and compared to show the feasibility of this proposal.
