Unaltered Optical Fiber as an Absolute Wavelength Reference for OFDR Systems
Interferometry Phase measurement
2015/5/25
We present a novel method of obtaining an absolute wavelength reference for OFDR measurements using Rayleigh backscatter from standard optical fiber. We report 1 GHz (8pm)accuracy.
2-cm spatial resolution over 40 km realized by bandwidth- division phase-noise-compensated OFDR
spatial resolution bandwidth- division noise-compensated OFDR
2015/5/18
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...
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.
