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.
