Scheme of experimental set-up: laser (L); mirror (M); beam splitter (BS); optical filter (F1); beams (B 0 ) and (B 1 ); photodiodes (D1) and (D2); hybrid LC cell (HC); oscilloscope (Os); generator (G); digital oscillographe (DO); computer (PC). The output diffraction orders are {0} and {1} the main orders; {−1} and {2} the first diffraction orders; {−2} and {3} the second diffraction orders. δ is the rotation angle of the cell
