Analysis Of Intrinsic Crosstalk In Tapped-Serial And Fabry-Perot Interferometric Fiber Sensor Arrays

Recently, we reported a new interferometric fiber sensor array architecture based on a transmissive tapped serial sensor network which, like the reflectometric Fabry-Perot array configuration, exhibits intrinsic optical crosstalk between the sensor elements in the array. In this paper we discuss the origin of these crosstalk effects in both array topologies, and present theoretical models which predict the level of crosstalk between individual sensor elements in each type of array.
