Extension of measurement range in OCDR based on double-modulation scheme
Mana Sakamoto, Tomoya Miyamae, Kohei Noda +3
We extend the measurement range of optical correlation-domain reflectometry (OCDR) by modulating the laser output frequency at two frequencies, while preserving spatial resolution.…
Fiber-optic temperature sensing probe using low-coherence light source
Kanon Toda, Kenta Otsubo, Kohei Noda +3
We present a new approach for measuring fiber tip temperature using low-coherence Brillouin optical correlation-domain reflectometry, which eliminates the need for an independent r…
Investigation of guidelines for improving spatial resolution in direct-modulation BOCDR
Seiga Ochi, Kouta Ozaki, Kohei Noda +3
The spatial resolution of direct-modulation Brillouin optical correlation-domain reflectometry is studied with respect to modulation amplitude and frequency. Results suggest that o…
High-resolution low-coherence Brillouin optical correlation-domain reflectometry with suppressed systematic error
Kenta Otsubo, Takaki Kiyozumi, Kohei Noda +3
We show that the systematic error unique to Brillouin optical correlation-domain reflectometry (BOCDR) can be effectively suppressed by use of low-coherence light, and demonstrate…
Observation of Rayleigh scattering by simplified optical correlation-domain reflectometry without frequency shifter
Tomoya Miyamae, Zhu Guangtao, Takaki Kiyozumi +4
We present a method for measuring the transmission loss of an optical fiber using simplified optical correlation-domain reflectometry. By intentionally lowering the spatial resolut…
