Long-Range Distributed Strain and Temperature Sensing with 40-cm Spatial Resolution Based on DPP-BOTDA Employing Optical Pre-Amplification and Simplex Coding
Fiber optics sensors Stimulated scattering
2011/5/25
Sub-meter resolution sensing has been achieved employing linear pre-amplification with Simplex-coded pulses employing DPP-BOTDA. Results demonstrate a spatial resolution of ~40 cm over 56km sensing fi...
10 cm spatial resolution and 20 km range full polarimetric reflectometry for distributed DGD measurement of high PMD fibres
polarimetric reflectometry distributed DGD measurement PMD fibres
2009/7/15
Full polarimetric reflectometry is realized with a spatial resolution of 10 cm over 20 km based on phase-noise compensated optical frequency domain reflectometry. Distributed DGD measurement of high P...
Sub-cm Spatial Resolution Reflectometry over 10 km Based on Phase Noise Compensated OFDR with Third Order Sideband Sweeping
Sub-cm Spatial Resolution Reflectometry Phase Noise Compensated OFDR
2009/7/15
We describe PNC-OFDR employing 3rd order sideband sweeping to realize a broader frequency sweep span. We achieved a sub-cm spatial resolution over a 10 km measurement range.
