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. ...
