Abstract
The disclosed deflector includes a thin film of liquid crystal on either side of which there is positioned at least one plane of electrodes, the assembly forming an array of elementary, quadripolar phase-shifters placed side by side, their electrodes being taken to different control potentials, generating a spatial modulation of the phase of the beam going through the deflector.
