Abstract
(EN) A sensor based on optical fiber technology is described. The sensor includes an elongate core for propagating light having an excitation wavelength; an interaction region that includes a fluorescent material for excitation by the propagated light to produce fluorescent light; and an interface region defining a boundary between the elongate core and the interaction region. The elongate core of the sensor is adapted to increase an intensity of the propagated light at the interface region to increase the amount of captured fluorescent light in the elongate core.
(FR) L'invention concerne un détecteur basé sur la technologie des fibres optiques. Le détecteur comprend une âme allongée pour propager de la lumière ayant une longueur d'onde d'excitation ; une région d'interaction qui comprend un matériau fluorescent pour une excitation par la lumière propagée afin de produire de la lumière fluorescente ; et une région d'interface définissant une frontière entre l'âme allongée et la région d'interaction. L'âme allongée du détecteur est apte à augmenter une intensité de la lumière propagée au niveau de la région d'interface pour augmenter la quantité de lumière fluorescente capturée dans l'âme allongée.
