Polarization map computed after propagating through a stress-engineered optic (SEO) at angles 0 through 24 degrees. The ellipses are overlaid on the intensity pattern after the beam goes through the circular analyzer, which blocks the RHC polarized light. The handedness of each polarization ellipse is color coded (green: right handed, red: left handed). Bottom panel illustrates the contour lines of equal ellipticity overlaid on the color coded azimuthal angle of each polarization ellipse on the Poincaré sphere.
