ABSTRACT:
An optical beam steering device for steering a beam of light includes a first window having a common electrode, a second window having a plurality of control electrodes, and a layer of electro-optical material intermediate the first and second windows. The common electrode, the control electrodes, and the electro-optical material form an array of phase shifters within the optical array. Each phase shifter has a width substantially greater than a wavelength of the beam of light. Also included is a means for establishing an effective position of the phase shifters so that a single beam of light of peak intensity exits the optical array where the single beam of light is steerable through a predetermined angle.
