Abstract: Pointing and positioning system of light beams and images including a plurality of cycloidal diffractive waveplates, each waveplate capable of deviating a generally broadband light beam over a predetermined angle. The lateral translation and deviation angles of the light beams are controlled by controlling the relative distance, rotational position, and the diffractive efficiency of a least one in the plurality of waveplates.
