Abstract
Reflectometric vibration measurement system to monitor multiphase flows in production wells or pipelines using multimode fibers comprising: —a sensing multimode optical fiber; —an optical source with at least one fiber output port, which generates optical pulses which are to be sent to the sensing fiber; —an optical receiver with at least one multimode fiber input port; —an optical device with at least 3 multimode fiber ports, in which one port is connected to the optical source, one port to the optical receiver, and one port to the sensing multimode fiber; —a system for processing the output signals from the optical receiver, further comprising more than one spatial mode filter. A process for reconfiguring an optical reflectometry system which has already been installed in a monitoring structure is also described.
