A quasi-distributed temperature sensor interrogated by optical frequency-domain reflectometer
(IOP Publishing, 2011-11)
This paper presents the analysis of a quasi-distributed sensor based on the concatenation of identical low-reflective fiber Bragg gratings. We experimentally demonstrated a temperature sensor using ten cascaded gratings ...
Infrared radiation detector interrogated by optical frequency-domain reflectometer
We experimentally demonstrated a fast infrared (IR) radiation sensor. It is capable of measuring IR radiation independently from the environmental temperature fluctuations. Experimental work shows that this IR detection ...
Complete analysis of multireflection and spectral-shadowing crosstalks in a quasi-distributed fiber sensor interrogated by OFDR
We present the analysis of a quasi-distributed fiber sensor based on the concatenation of identical low-reflective fiber Bragg gratings (FBGs) taking into account both multireflection and spectral-shadowing crosstalks. ...
Analytical investigation of a novel interrogation approach of fiber Bragg grating sensors using Optical Frequency Domain Reflectometry
This work presents a novel approach in interrogating Polarization Dependent Loss (PDL) of cascaded identical FBGs using Optical Frequency Domain Reflectometer (OFDR). The fundamentals of both polarisation properties of ...
