Abstract

In this paper, we demonstrate the use of a graded-index perfluorinated optical fiber (GI-POF) for distributed static and dynamic strain measurements. The system is based on a Coherent Optical Time-Domain Reflectometry (C-OTDR) configuration operating at the wavelength of 850 nm. Static strain measurements are carried out by exploiting the increase of the backscatter Rayleigh coefficient consequent to the application of a tensile strain. Dynamic strain (vibration) measurements are also detected along the same fiber, exploiting the vibration-induced changes in the backscatter Rayleigh intensity time-domain trace.
