Abstract: A distributed sensor system including an optical source (100) having a short coherence length for optionally continuously monitoring each sensor in the system. In one preferred embodiment, an array of fiber-optic sensors (110) are organized in a ladder configuration, with the sensors positioned in spaced relation and defining the rungs of the ladder. Light transmitted through the sensors is multiplexed onto a return arm (114) of the ladder, with sensor spacing being such that interference between light from different sensors is prevented. The multiplexed signals are received by an optical fiber receiver (118, 120) which couples the mutiplexed light with an interfering optical reference signal to produce a phase difference signal representing conditions influencing selected sensors. Embodiments are disclosed for use of either pulsed or continuous wave light sources. In another preferred embodiment, the sensors comprise a plurality of interferometers (404,406) connected in series configuration by a common optical fiber (402), which provides multiplexed output signals from the sensors to another plurality of interferometers (418, 420) comprising receivers. Functional equivalents of the series configuration provide sensors and receivers comprising birefringent or two-mode fiber. The optical path length differences between each pair of sensor arms (409, 410, 411 and 412) are selected to prevent interference between the multiplexed sensor output signals from the various sensors. The optical path lengths through the sensors (404, 406) and receivers (418, 420) are structured so that each receiver (418, 420) produces a phase difference signal relating to conditions affecting light transmission through a specific sensor (404, 406). A phase and amplitude modulation technique is disclosed for providing heterodyned output signals from the dristributed sensor system.

Abstract: Comparé aux gyroscopes à fibre optique de l'art antérieur, cet appareil se caractérise par une stabilité et une reproductibilité améliorées de sa polarisation, et par un taux fortement réduit d'extinction de la polarisation. Il comprend un substrat formé de préférence de verre de silice. Une première fibre optique pourvue d'une paire de coupleurs optiques espacés de couplage à une deuxième et à une troisième fibres est rigidement montée sur le substrat. Des surfaces planes sont formées dans des régions prédéterminées de la gaine des fibres fixées. Les coupleurs optiques, les polariseurs et les autres composants utilisés dans un détecteur de rotation sont agencés sur les surfaces planes de la gaine desdites fibres. Afin d'éliminer les composants indésirables de polarisation linéaire des signaux optiques guidés par les fibres, tout en permettant à un composant voulu de polarisation linéaire de se propager sans atténuation, l'axe de transmission des polariseurs formés sur les fibres est aligné avec un axe de biréfringence de la fibre correspondante. Un enroulement de fibre optique détecteur de la vitesse angulaire guide la lumière dans les deux sens entre la première et la troisième fibres optiques, alors que la première et la deuxième fibres optiques coopèrent avec le deuxième coupleur optique afin d'introduire des signaux optiques se propageant en sens inverse dans l'enroulement détecteur. Les coupleurs couplent également des signaux optiques se propageant en sens inverse afin de produire des signaux d'interférence qui constituent des mesures de la vitesse angulaire.
