Method A—sensor-based vectorial adaptive optics. a Random aberration case, showing V-AO off, phase AO only, and V-AO on. The vector field SOP profile, phase on the DM, profile of the foci are given. b SOP comparison on the Poincaré sphere of a sampled line of the vector fields of V-AO on and off status. Intensity comparison of a sampled line of different focus is presented as well. c V-AO off vs. V-AO on status of aberration correction for the GRIN objective lens. SOP distributions, DM phase patterns, and focus spot profiles are given. The red side of the colormap used for the SOP illustration represents right handedness while blue side is left handed. The ellipticity is illustrated via the shape of the ellipse. Pure linear SOP is shown as a green line with appropriate orientation
