    Abstract: An optical sensing system detects pressure through attenuation of light in an optical fiber. The weight and position of a load on a mat including multiple optical fibers may be determined; for example, such a mat may be used in an automobile seat to determine theses parameters for a passenger in the seat. This information can be presented to an airbag deployment system to easily enable the airbag to be deployed or suppressed in a manner sensitive to the weight and position of the occupant. This methodology allows loads, load movement, and load position to be detected in vehicles. In applications for vehicles such as aircraft or boats, sensing weight, position and movement of cargo can warn an operator or pilot in sufficient time to correct dangerous shifts in weight within the cargo portion of the vehicle or to modify the operation of the vehicle to compensate for such shifts.

    Abstract: Stresses and strains on a solid surface subject to a fluid flow are dynamically measured based on a shift of optical resonances of a micro-resonator. The elastic deformation and refractive index change of a micro-resonator due to mechanical stress is exploited. With this approach, mechanical deformations in the order of a nanometer can be detected and related to shear stress.

    Abstract: A fiber optic polarimetric strain sensor and associated data acquisition system capable of all-optical measurements of physical parameters, such as structural strain, gas and liquid pressure, acceleration and vibration, gas and liquid flow rate, and force without fire and explosion hazards associated with conventional strain gage technologies, such as resistance foil strain gages. The polarimetric strain sensor houses a sensitive element—a length of single mode optic fiber—changing polarization of a single-mode optical signal running in the fiber under some mechanical affects, specifically twisting and radial compressing. A linearly-polarized light passes the sensor, which causes polarization deviation of the light, particularly, polarization plane rotation under mentioned above twisting or compressive stresses applied to a sensitive element of the sensor. A multi-channel time division multiplexing data acquisition system that includes polarization analyzer indicates the polarization state deviation caused by the strain, so allow measuring the parameters. The invention may be embodied for measurements of any phenomenon that can be transformed in stress on an optical fiber.

    Abstract: A fiber optic sensor is also disclosed for measuring or detecting the prece of an environmental field condition such as under-water acoustic perturbations. The sensor includes a force transfer transducer, which is enclosed within a shell, with a pressure equalizer for equalizing the interior and exterior shell pressures. An optical fiber is coiled about the transducer. An optical detector detects stress or strain in the optical fiber, resulting from external perturbations. The sensor is able to operate at various depths or altitudes. Pressure equalization enables the isolation of dynamic external perturbations from other pressure variations. For this purpose, a pressure equalizing valve may be used to allow the equalization of slow changes in static pressures, and the detection of higher frequency perturbations which might emanate from a target source.
