摘要:
The present invention discloses a sensor which reacts on influences from an environment, the sensor comprising a zero-order diffractive color filter, the zero-order diffractive color filter comprising a high-index waveguide layer, a zero-order diffractive grating structure and a layer of an reactive material, wherein the reactive material is in contact with the environment and wherein the reactive material changes its optical properties upon interaction with the environment and wherein the reactive material is embedded in the waveguide layer and/or the reactive material is located at a maximum distance d from the waveguide layer, whereby the distancing is effected by an intra layer having a low index of refraction.

The present invention discloses a sensor (16000) which reacts on influences from an environment, the sensor comprising a zero-order diffractive color filter (16400), the zero-order diffractive color filter (16400) comprising a high-index waveguide layer (16300), a zero-order diffractive grating structure and a layer of an reactive material (16500), wherein the reactive material (16500) is in contact with the environment and wherein the reactive material (16500) changes its optical properties upon interaction with the environment and wherein the reactive material (16500) is embedded in the waveguide layer (16300) and/or the reactive material (16500) is located at a maximum distance (d) from the waveguide layer (16300), whereby the distancing is effected by an intra layer (16200) having a low index of refraction.
摘要:
La présente invention concerne un dispositif optique comprenant un premier (8) et un deuxième (9) polariseurs, agencés pour pouvoir évoluer entre un premier état dans lequel les directions de polarisation des premier et deuxième polariseurs sont parallèles et un deuxième état dans lequel les directions de polarisation des premier et deuxième polariseurs sont perpendiculaires. Selon l'invention, au moins un des polariseurs comporte une structure sub-micrométrique (18) anti-réfléchissante réalisée à sa surface et en ce que chaque polariseur est disposé sur un substrat (12) ayant un indice de réfraction inférieur à 1,77.
