Abstract

Integrating fiber optic sensors offer the potential to monitor large spatial extents due to their geometric flexibility. To date, this potential has not been widely exploited. By increasing the length of an integrating fiber optic sensor, its gain and/or gauge length can be increased. In addition, by configuring the sensor to a spatial distribution of some parameter field of interest, the antenna gain of the sensor will provide selectivity for that particular distribution and in effect, act as a preprocessor. In this paper we will discuss the theoretical aspects of antenna gain using spatially distributed long gauge length integrating fiber optic sensors. We will then review potential applications including vibration mode filtering, vehicle identification and seismic/nuclear test detection which have been reported. Finally, we will discuss the future directions that the technology might take.
