Abstract

We demonstrate a fiber-optic interferometric sensor array based on the in-line Fabry–Perot configuration, which uses fiber ring reflectors to effect the low-reflectivity elements required between each sensor section. The intrinsic optical cross talk that occurs between the sensor sections owing to multiple reflections is analyzed and compared with experimental results obtained with a four-sensor system.
