Accurate estimation of measurement position in Brillouin optical correlation-domain reflectometry based on Rayleigh noise spectral analysis
Keita Kikuchi, Ryo Inoue, Haruki Sasage +2
Brillouin optical correlation-domain reflectometry (BOCDR) is unique in its ability to measure distributed strain and temperature changes along a fiber under test (FUT) from a sing…
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…
High-speed high-resolution optical correlation-domain reflectometry without using electrical spectrum analyzer
Guangtao Zhu, Tomoya Miyamae, Kohei Noda +3
We propose a newly configured optical correlation-domain reflectometry (OCDR) without the use of an electrical spectrum analyzer (ESA) for high-speed distributed reflectivity measu…
Fiber-optic multimode interference sensing: comprehensive characterization and its potential for strain-insensitive temperature sensing
Kun Wang, Yosuke Mizuno, Xingchen Dong +5
A strain-insensitive temperature sensor based on multimode interference using standard multimode fibers (MMFs) is proposed according to the comprehensive study of the characteristi…
