Abstract

We present an intrinsic Fabry-Perot interferometric fiber-optic sensor for high density quasi-distributed temperature and strain measurement. The two internal partial reflection mirrors in such a sensor are formed by a pair of ultra-short fiber Bragg gratings. We experimentally demonstrate the multiplexing of 56 such sensors in a single fiber using a frequencydivision multiplexing scheme. We show that theoretically as many as 500 sensors can be multiplexed. We demonstrate the experimental results of the multiplexed sensors for quasi-distributed temperature and strain measurement and the temperature compensation of strain sensors.
