| Abstract: | The principle of operation of a novel fiber optics sensor system is demostrated. The extrinsic Fabry-Perot interferometric (EFPI) system is shown to possess wide dynamic range, high sensitivity and a real-time output signal. Applications of the EFPI system to high-performance civil structures are studied. Multiplexing of such sensors is achieved by employing the path matching method. |
