Characterization of strongly spun fibers with spin rate exceeding OFDR spatial resolution
spun fibers spin rate xceeding OFDR spatial resolution
2011/5/18
We describe an OFDR-based procedure to measure the spin of optical fibers with spin rates exceeding OFDR resolution. Fibers are twisted to locally unwind the spin and measurements are afterward reasse...
Fiber-Optic Brillouin Distributed Discrimination of Strain and Temperature with 11-cm Spatial Resolution Using Correlation-Based Continuous-Wave Technique
Fiber-Optic Brillouin Distributed Discrimination Temperature Spatial Resolution Continuous-Wave Technique
2008/8/3
11-cm spatial-resolution distributed discrimination of strain and temperature is realized by measuring the Brillouin frequency shift and the birefringence from monitoring the dynamic grating spectrum ...
