Abstract

The invention relates to an electro-optical phase modulator with a plurality of elements arranged between two substrates, whichare produced from an optically isotropic material which becomes optically anisotropic when an electrical field is applied, wherein for each of the elements respectively one electrode is arranged on both substrates and the electrodes can be individually controlled at least on one of the substrates.
