Title (EN) IMPROVED WAVEGUIDE AND ASSOCIATED SPECTROMETER ONBOARD AN AUTOMOBILE
(FR) GUIDE D'ONDE PERFECTIONNÉ ET SPECTROMÈTRE ASSOCIÉ EMBARQUÉ DANS UN VÉHICULE AUTOMOBILE
Abstract:
(EN) The invention relates to a device for measuring a spectrum of a light beam in a previously selected range of wavelengths, a device known as a spectrometer (10), the spectrum being generated by a fluid to be analysed, said spectrometer comprising: at least one light source (2); a measurement cell (4), comprising the fluid to be analysed; a measurement detector (5), placed on an optical path travelled by an optical measurement beam (22), said measurement beam (22) being emitted by the light source (2) and hitting the measurement cell (4); and a reference detector (6), placed on an optical path travelled by an optical reference beam (23), said reference beam (23) being emitted by the light source (2) and not hitting the measurement cell (4), characterised in that the spectrometer (10) is onboard an automobile and comprises a means (3) for shaping an incident optical beam emitted by said at least one light source (2) and for separating said optical beam into a measurement beam (22) and a reference beam (23) in the form of a waveguide.
(FR) L'invention concerne un dispositif de mesure d'un spectre d'un faisceau lumineux dans une plage de longueurs d'ondes préalablement choisie, dispositif appelé spectromètre (10), le spectre étant généré par un fluide à analyser, ledit spectromètre comportant : - au moins une source lumineuse (2), - une cellule de mesure (4), comportant le fluide à analyser, - un détecteur de mesure (5), placé sur un chemin optique parcouru par un faisceau optique de mesure (22), ledit faisceau de mesure (22) étant issu de la source lumineuse (2) et rencontrant la cellule de mesure (4), et - un détecteur de référence (6), placé sur un chemin optique parcouru par un faisceau optique de référence (23), ledit faisceau de référence (23) étant issu de la source lumineuse (2) et ne rencontrant pas la cellule de mesure (4), caractérisé en ce que le spectromètre (10) est embarqué dans un véhicule automobile et comporte un moyen (3) de mise en forme d'un faisceau optique incident issu de la au moins une source lumineuse (2) et de séparation dudit faisceau optique en un faisceau de mesure (22) et un faisceau de référence (23) sous la forme d'un guide d'onde.
