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...
2-cm spatial resolution over 40 km realized by bandwidth- division phase-noise-compensated OFDR
spatial resolution bandwidth- division noise-compensated OFDR
2011/5/18
We propose a bandwidth-division phase-noise-compensated optical frequency domain reflectometry technique. Using this approach, we realize a spatial resolution of 2 cm over 40 km in a normal laboratory...
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.
