Abstract

The ability to detect and locate the impact of foreign objects on the skins of vehicles or outer surfaces of other structures has considerable value for their associated health monitoring and adaptive control systems. If conventional impact location techniques are combined with integrating fiber optic sensors, it is possible to develop relatively simple systems for impact detection and location. The results of an investigation of one type of system implementation are presented in which impact generated acoustic signals are detected by statistical mode fiber optic vibration sensors embedded within a composite panel. Relative signal arrival times are then used to localize the impact. Correlation of impact magnitude and location with derived system values is carried out and an analysis of system performance is provided.
