Abstract(in Japanese) (See Japanese page)
Abstract(in English) We present a bandwidth-division phase-noise-compensated optical frequency domain reflectometry (PNC-OFDR) technique, which permits a fast sweep of the optical source frequency, making it possible to reduce the influence of environmental perturbation, the dominant factor to broaden the spatial resolution of frequency-domain reflectometry at a long measurement range after the compensation of optical source phase noise. By using this approach, we realize a spatial resolution of sub-cm over 40 km in a normal laboratory environment, and a spatial resolution of 5 cm at 39.2 km in a field trial.
