Abstract
This disclosure teaches a thin film beam steering system comprising either flat or tilted transparent electrodes on one side of the electro-optical crystal layer and a transparent ground electrode on the other side. There is an insulator between each adjacent electrode which can be inserted all the way or partially through the EO crystal layer. A mirror layer can also be attached to the ground electrode. The refractive index of the EO crystal layer is changeable as a function of varying an applied voltage generated by the voltage supply and applied to the EO crystal layer. The disclosure also includes bulk crystal beam steering systems to steer a beam in 2 dimensions and to a wider angle.
