Abstract
The invention relates to a retroreflector able to be placed in contact with an environment, comprising, by way of constituent material, a material enabling a parameter of said environment to be picked up, said material modifying the optical transmission properties of the retroreflector when said parameter is present, said retroreflector being able to receive an incident light beam via a first face and to reemit a light beam via said first face.
Claims23
A retroreflector adapted to be placed in contact with an environment, comprising, as a constitutive material, the material comprised between the faces of the retroreflector and also delimiting the latter, a porous material capturing a parameter of said environment, said parameter of said environment being a gas, said material inducing a modification of the optical transmission properties of the retroreflector in the presence of said parameter, and said retroreflector adapted to receive an incident light beam through a first face and to re-emit a light beam through said first face.
