Abstract

APPARATUS FOR ENHANCING THE QUALITY OF TRANSMISSION IN FIBER OPTIC CABLES USING INPUT AND OUTPUT OPTICAL ELEMENTS HAVING ELECTROMECHANICAL PROPERTIES. THE INPUT AND OUTPUT OPTICAL MEANS MAY BE OPTICAL WEDGES OF MATERIAL HAVING ELECTRO-OPTICAL PROPERTIES, FOR INSTANCE ELECTRO-OPTICAL MATERIALS SO THAT BY THE APPLICATION OF VOLTAGE TO THE ELEMENT, THE ANGLE BETWEEN THE ENTRANCE AND EXIT BEAM IS CHANGED. COMPENSATING OPTICAL MEANS ARE PROVIDED AT THE EXIT END AND THE SAME VOLTAGE IS APPLIED TO THE EXIT OPTICAL MEANS TO RESTORE THE IMAGE.
