Polarization holography in photocrosslinkable polymer liquid crystals films is described. By adjusting the polarization modes of the interference light beams, both “pure” polarization and surface relief gratings can be prepared. The Figure shows an optically polarized microscope image of a grating fabricated using orthogonal linear beams (arrows show direction of polarizers).
