    Abstract: A measurement tool configured to be run through a bore of a hydrocarbon well. The measurement tool includes a dielectric core, a controller disposed at a first end of the dielectric core, a first wire helically disposed about the dielectric core and extending from the controller to a first location a first distance from the controller, and a second wire helically disposed about the dielectric core and extending from the controller to a second location a second distance from the controller. The controller provides first and second input signals to the first and second wires, and receives first and second reflected signals from the first and second wires.

    Abstract: A pressure sensing cable in one embodiment includes a polarization maintaining (PM) optic fiber having a length; and a Fiber Bragg Grating (FBG) pair formed in the PM optic fiber. The FBG pair includes a first FBG formed at a location along the length of the optic fiber. The first FBG defines a first wavelength range at which the first FBG is reflective. The FBG pair also includes a second FBG spaced a distance from the first FBG to define a FBG cavity extending between the first FBG and the second FBG. The second FBG defines a second wavelength range at which the second FBG is reflective. The first wavelength range of the first FBG and the second wavelength range of the second FBG at least partially overlap.

    Abstract: A system for sensing the position of a movable object includes a polarization maintaining fiber configured to receive light from a light source; an optical system configured to rotate an angle of polarization of the light by a first predetermined angle; a low birefringence fiber connected to the optical system at a first end and having a mirror connected to a second end configured to reflect the light and rotate the angle of polarization at a second predetermined angle, the second end being configured to overlap a magnetic field of the a magnet attached to the object. The angle of polarization is rotated to a third predetermined angle proportional to at least one of the strength of the magnetic field and an amount of the overlap. The optical system is configured to decompose the third predetermined angle into a first component and a second component. A detector is configured to detect a differential between the first and second components indicative of the amount of the overlap.

    Abstract: Optical-based apparatus and method for sensing parameters in connection with an asset, such as a pipeline, are provided. At least two sites in an optical fiber may include a respective fiber grating arranged to have a respective optical response in a wavelength spectrum having a distinguishing feature indicative of a value of a respective local parameter at a respective grating site. The two fiber gratings may be further arranged to form, in combination with a respective portion of the optical fiber which extends between the two sites, respective optical backscatter portions that when combined with one another are effective to sense an optical change in the fiber portion between the sites indicative of a value of a distributed parameter. This is a parameter modality different from a parameter modality of the respective local parameters at the respective grating sites.

    Abstract: A fluid sensor that includes fluid sensitive interferometric nanostructure layers configured into an open-air resonant structure. Another fluid sensor also includes a polarization sensitive photodetector configured to detect optical contributions of different components of a fluid to the structure. A photonic sensor system includes: a photodetector; a signal processor coupled to the photodetector; and a sensor structure configured to provide fluid-response selectivity, spatially distribute light, and to receive light from a light source and convey light to the photodetector. A method of selective measurement of components in fluid in a process area includes: exposing a sensing structure to the fluid; interrogating the sensing structure with light from outside the process area; measuring a change in optical properties of the sensing structure; correlating the measured change to a stored value; and providing quantitative values of levels of the components in the fluid.
