Figure 5. The perfect vector beams generated in our experiment.

Three different polarization orders q = 1, 2, and 3 are displayed from left to right. First line shows the schematic polarization distributions (blue arrow diagrams), of which the experimental results are presented in each column respectively. Second row is the observed intensities which show the similar annular patterns as corresponding PV beams. Following rows are the polarizer examined intensities to verify the polarization distributions. Different axis orientations of polarizer 0°, 45°, 90°, and 135° (red arrows in the first column) are selected in experiment. Well agreements suggest that the obtained perfect beams are CVB, namely the PV beams here.
