Reflectometric two-mode elliptical-core fibre strain sensor with remote interrogation
Abstract
A reflectometric e-core fiber sensor configuration using a single fiber lead to guide light to and from the remote sensor location is presented. The use of an FM-based source interrogation techniques to obtain demodulated fiber strain measurements is demonstrated. The reflectometric approach has the advantage of operating via a single input/output fiber, which reduces fiber ingress/egress requirements for embedded sensor applications.
