The Stokes parameters pattern in Young's interference experiment with N pinholes are derived. Our calculations allow us to separate the information on the amplitude, absolute phase and polarization by mean of correlation functions; one correlation for intensity, one correlation function for the absolute phase and four correlation functions for the polarization (one for each Stokes Parameter). Then the visibility of certain Stokes parameter is the product of the correlation function of intensity, of absolute phase and of the polarization correlation function of that Stokes Parameter.
