Abstract
An ocean current detection device and method based on double-helix and double-core vibration fiber-optic cable, comprises a double-core fiber-optic cable and a φ-OTDR system; the double-core fiber-optic cable comprises a first and a second optical fiber core, provided symmetrically in the double helix structure. The terminate ends of the first and the second optical fiber core are connected, and the start end of the first or the second optical fiber core is connected with the φ-OTDR system. When measuring the ocean current characteristics in the target sea area, the double-core fiber-optic cable is provided underwater to generate vortex-induced vibration. The φ-OTDR system is provided for emitting laser towards the cable, receiving returned double-core vibration signals, extracting vibration characteristics from the double-core vibration signals to determine ocean current characteristics, including ocean current flow velocity and direction, to improve the detection accuracy.
