The apparatus includes a large diameter waveguide (LDW) sensor configured to be disposed in the borehole and to sense the parameter at one or more locations along the LDW sensor, the LDW sensor having an outer dimension greater than or equal to 0.25 mm and random variations of an optical property. An optical interrogator is coupled to the LDW sensor and configured to illuminate the LDW sensor with incident light at a swept frequency and to receive light from the large diameter waveguide due to Rayleigh scattering of the incident light by the random variations of the optical property along a length of the LDW sensor. The received light provides information for estimating the parameter and a location along the LDW sensor where the parameter was sensed.

摘要： The present invention is directed toward a fiber optic position and shape sensing device and the method of use. The device comprises an optical fiber means. The optical fiber means comprises either at least two single core optical fibers or a multicore optical fiber having at least two fiber cores. In either case, the fiber cores are spaced apart such that mode coupling between the fiber cores is minimized. An array of fiber Bragg gratings are disposed within each fiber core and a frequency domain reflectometer is positioned in an operable relationship to the optical fiber means. In use, the device is affixed to an object. Strain on the optical fiber is measured and the strain measurements correlated to local bend measurements. Local bend measurements are integrated to determine position and/or shape of the object.

摘要： A temperature sensing arrangement includes a member having a first coefficient of thermal expansion, and an optical fiber having a second coefficient of thermal expansion. The optical fiber is strain transmissively mounted to the member. And the first coefficient of thermal expansion is greater than the second coefficient of thermal expansion such that strain measurable in the optical fiber is correlatable to temperature changes in the member.
