摘要： A method and apparatus for obtaining a parameter of interest from an optical device placed along a fiber optic cable in a wellbore is disclosed. Light is propagated a light through the fiber optic cable from a light source. A first detector receives a first signal responsive to interaction of the propagated light and the optical device, wherein the first signal has a delay. A second detector receives a second signal and a digital delay device delays the received second signal. A sampling device obtains a selected signal from the first signal using the delayed second signal, and a processor determines the parameter of interest using the selected signal.

摘要： An interferometer has its performance enhanced by being suspended in a housing that is optionally evacuated. The frame that supports the interferometer is secured to a cover for the housing with a plurality of studs having mechanical vibration isolators. The frame comprises a support flange with a foam layer beneath the interferometer. An optics tray is disposed above the interferometer and holds the assembly to the support flange. The fibers that are connected to the interferometer enter the side of the housing and the entry is sealed off to allow the interior of the housing to be evacuated.
