Abstract (en)
[origin: WO2014012985A1] The invention relates to a method for measuring a medium of interest (20), which includes: arranging (701) the medium of interest between a light source (11) and a substrate (12) including a reflecting layer (121); illuminating (702) the substrate (12) by incident electromagnetic radiation (302) derived from the light source (11), the reflecting layer (121) producing a reflected radiation (303) from the incident electromagnetic radiation (302); measuring (703) an intensity of the reflected radiation by means of a sensor (13); detecting (704), from measurements carried out under constant illumination and measurement conditions, a change in the reflective properties of the assembly (40) including the medium of interest and the reflecting layer (121). The electromagnetic radiation emitted (301) is included within a spectral band of 350 nm to 1,000 nm, and the reflecting layer (121) has a reflectivity between 0.2 and 0.7 and a sensitivity greater than 1 x 10-3 nm-1 in the band.
