Modulation-Frequency Dependence of Spatial Resolution in Optical Correlation-Domain Reflectometry
Keisuke Motoda, Takaki Kiyozumi, Yosuke Mizuno
The spatial resolution of optical correlation-domain reflectometry (OCDR) has conventionally been described by an expression that is independent of the modulation frequency ,…

Beat-spectrum design for 100-km-range optical correlation-domain reflectometry with localized 15-cm resolution
Takaki Kiyozumi, Yuta Higa, Soshi Yoshida +4
Conventional optical correlation-domain reflectometry (OCDR) based on sinusoidal frequency modulation exhibits a coupling between measurement range and spatial resolution because b…
