Temperature sensor based on PNR in Sagnac interferometer

Not Accessible

Your library or personal account may give you access

Abstract

A temperature sensor based on polarization non-reciprocity (PNR) in fiber-optic Sagnac interferometer (FSI) was proposed. The experimental study was made primarily and the results agree with theory well. Discussion shows that this kind of temperature sensor can achieve high precision and have great application potential.
