ABSTRACT Summary form only given. We present a space-domain analogy of the rotating quarter waveplate method. Our method is based on a space-varying waveplate, which we realized as a computer-generated space-variant subwavelength dielectric grating. By performing a spatial Fourier analysis of the intensity transmitted through this polarization grating followed by an analyzer, we can measure all four Stokes parameter simultaneously, thereby enabling real-time polarimetry of polarized and partially polarized beams.
