Abstract
(EN)
An optical device (1) comprising: a light-permeable first electrode (13); a light-permeable second electrode (14); a refractive index adjustment layer (15) having a refractive index that changes as a result of an electric field and being capable of changing between a transparent state and state in which incident light is distributed; and an uneven layer (16) that makes the surface of the refractive index adjustment layer (15) uneven. The second electrode (14) forms an electrical pair with the first electrode (13). The refractive index adjustment layer (15) is arranged between the first electrode (13) and the second electrode (14) and includes liquid crystal. The optical device (1) comprises a structure (17) that forms the thickness of the refractive index adjustment layer (15). The structure (17) is adhered to the second electrode (14).

L'invention concerne un dispositif optique (1) comprenant : une première électrode perméable à la lumière (13); une seconde électrode perméable à la lumière (14); une couche de réglage d'indice de réfraction (15) ayant un indice de réfraction qui change sous l'action d'un champ électrique et étant apte à changer entre un état transparent et un état dans lequel une lumière incidente est distribuée; et une couche irrégulière (16) qui rend la surface de la couche de réglage d'indice de réfraction (15) irrégulière. La seconde électrode (14) forme une paire électrique avec la première électrode (13). La couche de réglage d'indice de réfraction (15) est agencée entre la première électrode (13) et la seconde électrode (14) et comprend des cristaux liquides. Le dispositif optique (1) comprend une structure (17) qui forme l'épaisseur de la couche de réglage d'indice de réfraction (15). La structure (17) est collée à la seconde électrode (14).
