Title
(EN) METHOD FOR ANALYSING A FLUID OF A MOTOR VEHICLE USING AN OPTICAL SENSOR
(FR) PROCEDE D'ANALYSE D'UN FLUIDE D'UN VEHICULE AUTOMOBILE A PARTIR D'UN CAPTEUR OPTIQUE
Abstract
(EN)
The present invention concerns a method for analysing a fluid of a motor vehicle, using an optical sensor (100) comprising a Fabry-Pérot interferometer (10) for performing spectral analysis of a light beam, a voltage generator (20) and power storage units (31, 32, 33). The method comprises successive steps of charging the storage units (31, 32, 33), by the generator (20), and supplying power to the interferometer (10), by the storage units (31, 32, 33).
(FR)
La présente invention a pour objet un procédé d'analyse d'un fluide d'un véhicule automobile à partir d'un capteur optique (100) comprenant un interféromètre (10) de Fabry-Pérot pour réaliser l'analyse spectrale d'un faisceau lumineux, un générateur de tension (20) et des unités de stockage (31, 32, 33) d'énergie électrique. Le procédé comprend des étapes successives de charge des unités de stockage (31, 32, 33) par le générateur (20) et d'alimentation en énergie électrique de l'interféromètre (10) par les unités de stockage (31, 32, 33).
