title = "Cost-effective high rate interrogation architecture for Fabry-Perot interferometric sensors",
abstract = "In this paper, the design and implementation of a cost-effective interrogation architecture, for dynamic strain monitoring of in-line Fabry-Perot interferometric (FPI) optical fiber sensors is presented. The common interrogation techniques for this type of sensors are based in the full spectrum analysis, which render them not adequate for dynamic/high frequency monitoring applications. In this work, we propose an alternative cost-effective solution, based on a simplified edge-filter technique, for the dynamic monitoring of FPI sensing devices. The FPI based sensor was produced from the recycling of optical fiber previously damaged by the catastrophic fuse effect using precise splicing techniques. A characterization was performed with two different devices, an optical spectrum analyzer (OSA) and the proposed device leading to similar behavior and sensitivity values.",
