Title (EN) OPTICAL SENSOR
(FR) CAPTEUR OPTIQUE
Abstract:
(EN) An optically transparent matrix comprising a molecule containing a hydroxyazobenzene group or its derivative embedded in the matrix. An optical system comprising the optically transparent matrix, an isomerizing light source, and means for measuring absorbance changes from the optically transparent matrix. A method for measuring the quantity of hydrogen bonding gaseous molecules.
(FR) Une matrice optiquement transparente comprend une molécule contenant un groupe hydroxyazobenzène ou son dérivé intégré dans la matrice. L'invention concerne également un système optique comprenant la matrice optiquement transparente, une source de lumière d'isomérisation, et des moyens pour mesurer des changements d'absorbance à partir de la matrice optiquement transparente. L'invention concerne également un procédé de mesure de la quantité de molécules gazeuses de liaison à l'hydrogène.
