We report on our first experimental comparison of polarization‐independent projection schemes using the liquid crystal polarization grating (LCPG) modulator as the active element. This recently‐demonstrated LC grating has unique diffraction properties, and we evaluate its performance using the bright‐ and dark‐field Schlieren configurations and consider its use with a TIR‐prism assembly. Each scheme shows promise for high‐brightness and good‐contrast projection for different applications.
