The optical system, which is comprised of a thin layer of ion conducting, macromolecular material, or solid polymer electrolyte sandwiched between two electrodes presenting each a conducting deposition carried by a support plate such that at least one of the conductor depositions and the associated support plate are transparent, is heated by applying between the conductor depositions of said electrodes an electric voltage signal of which at least one portion includes an alternating component which has an amplitude between 0.05 and 100 volts and a frequency lower than 5 kHz and preferably between 2 and 2000 Hz so as to generate within said optical system an alternating ionic current susceptible of producing a heating of the ion conducting macromolecular material by Joule effect. The optical system to be heated, which may be an electrochromium device, may have particularly a glazing type structure or a mirror type structure.

Le système optique à chauffer, qui peut être un dispositif électrochrome, peut avoir notamment une structure de type vitrage ou encore une structure de type miroir.
