Abstract
An electrically controllable optical component (10) comprises a transparent array of cells (3) and two transparent electrodes (5a, 5b) which are parallel and lying opposite each other on either side of the array of cells. Certain of the cells located between the two electrodes contain different electroactive materials, so that said cells exhibit different respective variations in at least one optical quantity in response to an electrical signal applied to the electrodes. An optical function is thus temporarily conferred on the component, resulting from gradients in the optical quantity that are formed parallel to the surface of the component.
