Fig. 4 — a–c Calculated (lines) and measured (circles) polarization trajectories on the Poincaré sphere realized at the wavelength of 800 nm by tuning the air gap T_a for different dynamic wave plate (DWP) orientations, illustrating the diversity of possible polarization transformations: a continuous linear polarization (LP) rotation realized by combining the DWP with a conventional quarter-wave plate (QWP) with the incident LP state |y > and DWP orientation θ_DWP = 45°, b various elliptical polarization transformations realized for different DWP orientations with the fixed incident LP state |y >, and c various elliptical polarization transformations realized for different incident LP states with the fixed DWP orientation θ_DWP = 45°. The green stars in (a–c) indicate respective incident LP states.
