    Abstract: A method of analyzing force on a surface is described including providing a pressure-sensitive medium, applying the force to the medium, determining any change in the medium as a result of the applied force, correlating the change in the medium with a pressure value, and analyzing the force value. The pressure-sensitive film may be scanned, each shade or color on the film assigned a pixel value corresponding with pressure values, and the total pixel area values measured to determine pressure characteristics, such as average pressure or total pressure area.

    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 fiber 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, strain values during loading and unloading of the vessel (5) are detected by the strain sensors (7; 16). The control system (1) generates a curve 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 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 fiber optic strain sensor (16) are also used with this method.

    Abstract: A fiber optic sensor system includes a first optical power source which icts a light pulse into an optical fiber loop system. The light pulse circulates in the optical fiber loop system at a circulation frequency. The optical fiber loop system includes a transducer which modulates the circulation frequency in response to detecting a changing physical condition, a filter, polarization controller, an isolator, and an optical fiber gain medium for amplifying the light pulse. A second optical power source provides optical energy to the optical fiber gain medium. A detector system transforms a portion of the light pulse received from the optical fiber loop system into an output signal representing the circulation frequency.

    Abstract: A description is given of a tactile sensor for measuring force with fine resolution which is based on a network of glass fiber optic interferometers. The counting of interference fringes as readout method makes available an inherently digital (incremental) output signal which allows the measured signal to be passed on optically free of interference to evaluation electronics and to data processing. In conjunction with a suitable elastic skin to accept the glass fiber network, the small glass fiber diameter (125 .mu.) and the user of the strain measurement technique employing glass fiber interferometers should make possible a tactile sensor comparable with the human sense of touch. The fields of application for such tactile sensors are robotics, prostheses and advanced controls at the man-machine interface.
