Abstract: The analytic calculation formula of the vector Fraunhofer diffraction of polarized light wave through-out rectangular aperture is derived with Rayleigh-Sommerfeld vector diffraction formula. Then Fraunhofer vector dif-fraction of elliptically polarized light throughout general aperture or sub-wavelength aperture cases are studied with simulation experiments, these can be used for the detection of the polarization degree of polarized light and polariza-tion imaging, etc. the vector diffraction and the diffraction situation of general aperture and sub-wavelength aperture is discussed. The simulations show that the calculation formula is valid and reliable, it can play a role in micro-op-tics, near-field optics, diffraction imaging, light beam transmission and transformation, and light information process-ing and so on.
