Abstract: For continuous monitoring of dynamic loads, including stresses and strains in large hull structures for vessels (5), a strain measurement system (2) is employed with fibre optic cables which connect optical strain sensors (7; 16) at different points in the hull structure. Optical signals for detection of stresses and strains are distributed to the strain sensors (7; 16) from an optical transmitter (11). The strain measurement system (2) is connected via a central monitoring unit (10) to a computer-implemented control system (1) which in turn is connected to a display and data presentation unit (4) and possibly other measurement systems (3). In a first operating mode in this method strain values during loading and unloading of the vessel (5) are detected by means of the strain sensors (7; 16). By means of the control system (1) a curve is generated which shows an average strain, and an alarm signal if the average strain exceeds a predetermined threshold which indicates an unacceptable level of strain. In a second operating mode when the vessel (5) is underway, strains are continuously detected by means of the strain sensors (7; 16). An alarm signal is generated if the average strain exceeds a predetermined threshold which indicates an unacceptable level of strain. A strain measurement system and a fibre optic strain sensor (16) for use with this method are also described.

Abstract: The aim of the invention is to provide a deformation sensor that requires no additional sensor for operational testing. The inventive deformation sensor consists of an optical transmission medium (UM1, UM2), several transmitting elements (S1, S2) which couple light of different wavelengths ( lambda 1, lambda 2) into the transmission medium (UM1, UM2); and several receiving elements (E1, E2) which selectively couple the transmitted light out of the transmission medium (UM1, UM2) according to wavelengths. An evaluating unit (AW) detects deviations between the output signals (a1, a2) for the receiving elements (E1, E2) and indicates defective functioning of the sensor if these deviations exceed a predetermined value. The receiving elements (E1, E2) can also react inversely. The invention is suitable for detecting a side crash.

Abstract: A strain transducer (14) is responsive to a deflection thereof for providing a detectable output signal having a characteristic that is expressive of the deflection. The transducer includes an optical fiber having an input port (16) for coupling to a source (18) of optical radiation and an output port (20) for coupling to a receiver (22) of the optical radiation. The optical fiber has at least one region (14') that has a radius of curvature that is equal to or less than a critical radius of curvature for the optical fiber. The at least one region includes a detectable loss in the optical signal in response to being deflected. The optical fiber is disposed within a plane and the detectable loss is shown to be greater for an out-of-plane deflection than for an in-plane deflection. The strain transducer is shown to be especially useful for inclusion within a laminated composite structure, such as a component of an aircraft wing.

Abstract: An optical fibre strain gauge (1) for an engineering structure e.g. a bridge, building, pipe, plant or the like, comprises: (a) a plurality of supports (8, 10) for the optical fibre that can be located on a surface of the structure and are spaced apart from one another over a part of the surface; and (b) at least one optical fibre (12) that is looped around the supports so that it extends between the supports, the optical fibre being fixed to the supports so that the length of the part of the fibre extending between the supports will vary in accordance with strain of the surface of the structure. The optical fibre(s) (12) can be looped around the supports (8, 10) a number of times, which enables the fibre(s) to be held more easily, and enables the strain gauge to incorporate a length of fibre significantly greater than the dimension of the area of the structure that is being monitored. The fibre(s) will normally contain reflectors such as Bragg gratings to enable signals to be monitored.

Abstract: An optical fibre (7) exhibits varying transmission characteristics in different strain states and can have an S-shaped microbend. For producing such a fibre it is heated locally in a small region, as viewed in the longidutinal direction of the fibre, and then the portions of the fibre (1) located at the two sides of the heated region are displaced in relation to each other in a transverse direction in relation to the longitudinal direction of the fibre. It can be performed in a conventional fusion-splicing apparatus for optical fibres. Alternatively, a laser can be used as a heating source, what is particularly suitable for processing optical fibres having longitudinal cavities in order to infer to it similar transmission characteristics. The optical fibres produced by this method are suited for use as sensors, e.g. strain gauges.
