FIELD: physics.
SUBSTANCE: sensor is prepared by way of formation on a substrate of an ordered periodical mass of elements, application of a polymer matrix coating onto the particles mass, the matrix consolidation for the particles mass fixation in the matrix and bringing the fixed mass in contact with the activator; the activator impact shifts the wavelength of radiation diffracted by the sensor from the first wavelength to the second wavelength.
EFFECT: lower cost.
