Large-angle beam deflector using liquid crystals
A new type of beam deflector is described which involves an electrically induced variation of the optic axis across a liquid-crystal cell. Light polarised in the plane of the optic axis can be deflected through a half-angle of 20°, with slew rates in excess of 200°/s.
