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
2015/7/15
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
2015/7/15
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.
Investigation of the topography of magnetron-deposited Cu/Ni multilayers by X-ray reflectometry and atomic force microscopy
multilayers Cu/Ni X-ray reflectometry (XRR)
2011/5/11
This paper presents the results of research of Cu/Ni multilayers magnetron-deposited on an Si (100) substrate. The thickness of Cu sublayers was identical in all multilayers and equalled 2 nm. The th...
Evolution of Backscattered Polarization in High-PMD Fibres Measured by Phase-Noise Compensated Optical Frequency Domain Reflectometry
Backscattered Polarization High-PMD Fibres Measured Phase-Noise Compensated Optical Frequency Domain Reflectometry
2015/8/4
The evolution of backscattered polarization in high-PMD fibres is measured by phase-noise compensated optical frequency domain reflectometry with a 25 cm spatial resolution and a 7.5 km measurement ra...
40-km Range, 1-m Resolution Measurement Based on Phase-noise- compensated Coherent Optical Frequency Domain Reflectometry
Resolution Measurement Phase-noise-compensated Coherent Optical Frequency Domain Reflectometry
2015/8/4
We present 40-km range, 1-m spatial resolution and highly sensitive measurement based on phase-noise-compensated OFDR that employs a concatenative reference method.
Enlargement of Measurement Range of Brillouin Optical Correlation-Domain Reflectometry Based on Temporal Gating Scheme
Measurement Range Brillouin Optical Temporal Gating Scheme
2015/8/3
We propose a new method to enlarge the measurement range of Brillouin optical correlation-domain reflectometry (BOCDR). 66-cm spatial resolution and 1-km measurement range were obtained simultaneously...
