Abstract
A planar electro-optical light deflector is operable to provide a plurality of beam positions and is characterized in that the same is a Bragg deflector having several adjacently-disposed electrode structures which are separately activatable, have respective different grid constants and are disposed on a layer waveguide inclined in such a manner that the light impinges on the respective electrode structures under respective Bragg angles, whereby the layer waveguide is capable of excitation over a width which corresponds to the totality of all electrode structures.
