Interrogation of a remote elliptical-core dual-mode fiber strain sensor by using a tandem interferometer
Abstract:
We report on the interrogation of a lead-insensitive dual-mode fiber sensor using a white-light interferometric technique with a multimode laser-diode source. An elliptical-core dual-mode fiber acts as a remote-sensing interferometer, and a second dual-mode fiber acts as a receiver interferometer. We establish the sensor design for optimized performance and demonstrate the capability of accurate detection of periodic strain signals in the presence of, e.g., temperature-induced low-frequency phase drifts.
