Abstract: The embankment monitoring system comprises an optic sensor chain (10) and an interrogator (20). The optic sensor chain (10) comprises a series of intrinsic fiber optic sensors (12) that are mutually spaced with respect to each other in a longitudinal direction of the optic sensor chain and at least one optic fiber (14) to optically connect the plurality of intrinsic fiber optic sensors to the interrogator. The interrogator is configured to issue an optic interrogation signal and the intrinsic fiber optic sensors are configured to respond to the optic interrogation signal with an optic measurement signal that is indicative for at least one physical parameter (P1) sensed by the intrinsic fiber optic sensors. The interrogator is further configured to process the optic measurement signals of the intrinsic fiber optic sensors to estimate a depth (d) as a function of a position (p) along said optic sensor chain (10).

Abstract: The invention relates to an optical sensor device comprising a reference body and at least one sensing transducer. The sensing transducer is arranged for receiving an input action, and is movably arranged relative to the reference body for moving relative to the reference body in response to the input action. The device further comprises an optical fiber and one or more transmission arms including a first transmission arm. The optical fiber comprises an intrinsic fiber optic sensor. The optical fiber is connected with a first connecting part thereof to the first transmission arm and with a second connecting part thereof to an element exterior to said first transmission arm. The first connecting part and the second connecting part are on either side of the intrinsic fiber optic sensor. For receiving the input action, a base of the first transmission arm is connected at a first part thereof with the reference body and with a second part thereof with the sensing transducer. The optical fiber is connected at a location along the first transmission arm remote from the base thereby converting the input action received by the sensing transducer into a sensing action applied to the optical fiber such as to modify strain in the optical fiber dependent on said input action.

Abstract: The airport monitoring system (1) for monitoring an airport territory (5), comprises an airport territory surface and an optic sensor system (70, 72a, . . . , 72e, 100). The airport territory surface has a traffic infrastructure to support conveyance elements of a vehicle (90), e.g. an aircraft or a service vehicle, therewith allowing movements of the vehicle over the airport territory surface.The optic sensor system (70, 72a, . . . , 72e, 100), includes an interrogator module (100) and fiber optic sensors (72a, . . . , 72e) coupled thereto. The fiber optic sensors are arranged below the airport territory surface and have a respective plurality of optic strain-sensor elements (722) with mutually different optical characteristics.The interrogator module (100) transmits optical interrogation signals into the fiber optic sensors and receives respective response optical signals that have been modulated by the fiber optic sensors based on their optical characteristics. The interrogator module (100) identifies changes in the optical characteristics of the received respective response optical signals resulting from strains induced in the optic strain-sensor elements as a result of pressure exerted by a conveyance element (92) of a vehicle (90) on the airport territory surface (51) near a fiber optic sensor.
