ABSTRACT:
The electro-optical switch in accordance with the invention comprises one or more nematic crystals (7) for the deflection of polarized light. In order to enable deflection of a light beam in two perpendicular directions by means of two electrically controllable crystals, the beam (4) of unpolarized light is converted into a beam (6) of polarized light in a low-loss manner.
