摘 要：Fiber optic sensing is a rapidly developing emergent technology in which a number of systems are currently in development. Potential applications at the U.S. Army Research Laboratory (ARL) include ballistic shock sensors, loading rate strain sensors, acoustic emission crack detectors, fiber laser vibrometers, velocity sensors for structural vibration, and others. This report provides a comprehensive overview of the fiber sensor technology, interferometric implementations, and the range of sensor system platforms that can be applied to improve ARL s ability to support its test requirements.
