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…
Expected number of zeros of random power series with finitely dependent Gaussian coefficients
Kohei Noda, Tomoyuki Shirai
We are concerned with zeros of random power series with coefficients being a stationary, centered, complex Gaussian process. We show that the expected number of zeros in every smoo…
