Title
(EN) PHOTONIC MEASUREMENT INSTRUMENT USING NON-SOLARIZING UV GRADE FIBER OPTICS
(FR) INSTRUMENT DE MESURE PHOTONIQUE UTILISANT DES FIBRES OPTIQUES DE QUALITÉ UV NON SOLARISANTES
Abstract
(EN) A photonic measurement system, such as an atomic absorption spectrometer, includes source, sample and detection modules that are interconnected by fiber optic cables. A first set of fiber optic cables guides light from one or more light sources in the source module to each of at least two analysis chambers in the sample module. A second set of fiber optic cables guides light from the analysis chambers to a detector in the detection module. The detector provides to a processing sub-system signals that correspond to intensities of the guided light. One analysis chamber is selected to perform a sample analysis at a given time, and the processing sub-system processes the signals associated with the selected analysis chamber as measurement signals. The processing sub-system may further process the signals associated with a given non-selected analysis chamber as reference signals.
(FR) L'invention concerne un instrument de mesure photonique tel qu'un spectromètre d'absorption atomique, qui comprend des modules de source, d'échantillon et de détection interconnectés par des câbles à fibre optique. Un premier ensemble des câbles à fibre optique guide la lumière provenant d'une ou de plusieurs sources lumineuses du module de source vers chacune d'au moins deux chambres d'analyse du module d'échantillon. Un deuxième ensemble des câbles à fibre optique guide la lumière provenant des chambres d'analyse vers un détecteur du module de détection. Le détecteur produit des signaux de sous-système de traitement qui correspondent à des intensités de la lumière guidée. Une chambre d'analyse est sélectionnée pour mettre en œuvre une analyse d'échantillon à un moment donné, et le sous-système de traitement traite les signaux associés à la chambre d'analyse sélectionnée comme des signaux de mesure. Le sous-système de traitement traite ensuite les signaux associés à une chambre d'analyse non sélectionnée donnée comme des signaux de référence.
