Title
(EN) APPARATUS FOR MEASURING FLUORESCENT MATERIAL IN A LIQUID
(FR) APPAREIL DE MESURE DE MATIÈRE FLUORESCENTE CONTENUE DANS UN LIQUIDE
Abstract
(EN)
An apparatus (10) for measuring, in particular, the amount of oil present in a quantity of water. The apparatus comprises a measurement chamber (12) having an optical window (18) through which an excitation signal may be transmitted and fluorescent light may be detected. The apparatus further includes an ultrasonic transducer (34) coupled to the measurement chamber and having a pair of channels (44,45) formed therein, the channels opening onto the measurement window (18). A respective light guide (28) is inserted into each channel, one light guide being arranged to deliver the excitation signal into the chamber through the measurement window, the other being arranged to carry fluorescent light from the chamber.
(FR)
L'invention concerne un appareil (10) qui permet de mesurer, en particulier, la quantité d'huile présente dans une certaine quantité d'eau. L'appareil comprend une chambre de mesure (12) dotée d'une fenêtre optique (18) qui permet à la fois la transmission d'un signal d'excitation et la détection d'une lumière fluorescente. De plus, l'appareil comprend un transducteur ultrasonique (34) couplé à la chambre de mesure et dans lequel est formée une paire de canaux (44, 45) débouchant sur la fenêtre de mesure (18). Un guide de lumière (28) respectif est introduit dans chaque canal, un premier guide de lumière étant conçu pour acheminer le signal d'excitation jusqu'à la chambre de mesure, en passant par la fenêtre optique, et le second étant conçu pour transporter la lumière fluorescent hors de la chambre.
