V. Bhatia et al., OPTICAL-FIBER BASED ABSOLUTE EXTRINSIC FABRY-PEROT INTERFEROMETRIC SENSING SYSTEM, Measurement science & technology, 7(1), 1996, pp. 58-61
The design and principle of operation of a novel fibre optic sensing s
ystem is presented. The absolute extrinsic Fabry-Perot interferometric
(AEFPI) system is shown to possess high sensitivity, wide dynamic ran
ge 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.
