Abstract

PURPOSE: To miniaturize an electrooptical modulation system by providing transparent or translucent electrodes on both sides of a film made of a vinylidene fluoride type copolymer as one component.
CONSTITUTION: On both surfaces of uniaxially drawn film 1 of a VDF copolymer obtained by copolymerizing a mixed monomer of vinylidene fluoride monomer VDF and a monomer (comonomer) which can be copolymerized with vinylidene fluoride, transparent electrodes 2 and 2' are vapor-deposited and applied with a voltage from variable high-voltage DC electric power source 3. Incident light 4 to film 1 is changed into modulated light as birefringent beam 5 by the voltage applied to electrodes 2 and 2' and it is detected by a diode, etc., and recorded. Further, the VDF copolymer includes ≥30mol% vinylidene fluoride and ≤70mol% vinylidene fluoride.
