If an object field is assumed to possess only polarization direction structure, the resulting interference field intensity will be given by I (x,y)=E20E2 (x ,y) cost oc (x ,y) +2E0E (x ,y) cos oc (x,y)cosd (x, y) , (1) where E0 is the reference field amplitude, E and 6, cc , are the random values of the amplitude, phase and polarization direction, that depend on coordinates.
