Visualization of the pupils for diattenuation and retardance when their repeatabilities equal to their true values. a A SUT pupil of true diattenuation decomposed from a pupil of the Jones matrix. The Jones matrix pupil has diattenuation of 0.5% RMS OZP and retardance of 0.5∘ RMS OZP. b The mean of the measured pupil of diattenuation and c the repeatability pupil of diattenuation reconstructed from the first 72 terms of the OZP expansion over 100 trials. d A pupil of true diattenuation after the Jones matrix pupil decomposition. The Jones pupil has diattenuation of 0.8% RMS OZP and retardance of 0.3∘ RMS OZP. e The mean of the measured pupil of retardance and f the repeatability pupil of retardance from reconstruction over 100 trials. From inside to outside, concentric circles correspond to angles at the objective of 5∘,15∘ and 25∘. White directional lines denote the azimuthal angles across the pupils
