Abstract
The design and principle of operation of a novel fibre optic sensing system is presented. The absolute extrinsic Fabry - Pérot interferometric (AEFPI) system is shown to possess high sensitivity, wide dynamic range and a real-time output signal. Applications of the AEFPI system to high-performance civil structures are suggested. Multiplexing of many such sensors is achieved by employing the path matching configuration.Keywords
