The results show that the spatial coherence of incident field has a strong influence on the polarization state of ouput beam. The polazrization degree of output beam depends on the ratial between the spatial correlation lengths of two components of incident field. Radial-distributions of the polarization degree of output beam are different for defferent Fourier transform system.
