More Information
Summary:Various embodiments include apparatus and methods structured to interrogate a plurality of sensor assemblies, where each sensor assembly may have one or more transmissive optical sensors. The plurality of sensor assemblies can be arranged to couple between two optical fibers. The interrogation can include generating optical signals to each sensor assembly such that each sensor assembly can be selectively and individually interrogated using semiconductor optical amplifiers. Additional apparatus, systems, and methods are disclosed. L'invention concerne, selon divers modes de réalisation, un appareil et des procédés structurés pour interroger une pluralité d'ensembles de capteurs, chaque ensemble de capteurs pouvant posséder un ou plusieurs capteurs optiques transmissifs. La pluralité d'ensembles de capteurs peut être agencée pour se coupler entre deux fibres optiques. L'interrogation peut consister à générer des signaux optiques vers chaque ensemble de capteurs de sorte que chaque ensemble de capteurs puisse être interrogé sélectivement et individuellement à l'aide d'amplificateurs optiques semi-conducteurs. Des appareils, des systèmes et des procédés supplémentaires sont également décrits.
