Abstract
Present day sensing of the vibration fields associated with large flexible structures is carried out with arrays of point sensors (accelerometers). The vibration field is then determined from interpolation of the array point values. Fiber optic sensors that provide outputs proportional to the line integral of the physical deviation of the fiber from a straight line have been demonstrated. These sensors offer the potential for cost effective real time monitoring of structural vibration fields for damage detection and other purposes. In this paper, the results obtained from the monitoring of a large linear structure using a fiber optic statistical mode sensor are presented. These results are then compared to point measurements made by accelerometers attached to the structure.
