Spatially Resolved Fiber Bragg Grating Sensing Using Wavelength Scanning Incoherent OFDR

Not Accessible

Your library or personal account may give you access

Abstract

A spatially resolved interrogation of fiber Bragg grating sensors, using incoherent optical frequency domain reflectometry and wavelength scanning is demonstrated. The method potentially allows a spectrally denser sensor packing and provides centimeter range resolution.
