摘要： An insertion and extraction tool for a fiber optic connector is provided. The tool includes a first frame member, second frame member, and a pivot connection. The pivot connection secures the first and second frame members to one another for movement between an open position and a closed position. The frame members define tips at one side of the pivot connection and handles at an opposite side of the pivot connection. The frame members, at least at the tips, have a cross sectional width equal to or smaller than the fiber optic connector. The frame members are configured so that the tips define a plurality of discrete gripping regions.

摘要： Small profile apparatus for pressure and/or temperature sensing within a wellbore are provided. The apparatus may include optical sensing assemblies designed for inclusion in traditional or coiled production tubing deployments and suitable for use in high pressure, high temperature environments. One example assembly generally includes an outer housing, an inner housing at least partially disposed in the outer housing, a port for fluid communication between an internal volume of the inner housing and a volume external to the outer housing, and a large diameter optical waveguide disposed in the internal volume of the inner housing. The waveguide includes a first portion with a first grating and a second portion with a second grating, wherein the outer diameter of the large diameter optical waveguide is at least 300 μm.

摘要： Small profile apparatus for pressure and/or temperature sensing within a wellbore are provided. The apparatus may include optical sensing assemblies designed for inclusion in traditional or coiled production tubing deployments and suitable for use in high pressure, high temperature environments. One example assembly generally includes a housing having a divider for separating a first volume from a second volume inside the housing, a compressible element disposed in the first volume, wherein a first end of the compressible element is coupled to the divider and a second of the compressible element is sealed, and a large diameter optical waveguide disposed in an internal volume of the compressible element. The waveguide typically includes a first portion with a first grating and a second portion with a second grating, wherein the first portion has a greater outer diameter than the second portion.

摘要： A fiber optical superconducting nanowire detector with increased detector efficiency, fabricated directly on the tip of the input optical fiber. The fabrication on the tip of the fiber allows precise alignment of the detector to the fiber core, where the field mode is maximal. This construction maximizes the coupling efficiency to close to unity, without the need for complex alignment procedures, such as the need to align the input fiber with a previously fabricated device. The device includes a high-Q optical cavity, such that any photon entering the device will be reflected to and fro within the cavity numerous times, thereby increasing its chances of absorption by the nanowire structure. This is achieved by using dedicated cavity mirrors with very high reflectivity, with the meander nanowire structure contained within the cavity between the end mirrors, such that photons impinge on the nanowire structure with every traverse of the cavity.

摘要： A fiber optic sensor is embedded in an integral housing block formed by molding or extrusion. The housing block has a mounting surface for attachment to a wind turbine component by adhesive or mechanical connection. In an arrangement where the sensor is to be isolated from strains on the component, the housing block may be mounted on the component by means of a smaller mounting portion, joining the mounting portion at a neck region.
