摘要： An optical fiber containing one or more random modulations capable of reflecting one or more random wavelengths of light passing through the optical fiber is provided. Each modulation is a section of the optical fiber in which the refractive index has been modified or a section of random refractive index optical fiber that has been spliced into the optical fiber. The optical fiber is produced by modifying the refractive index of at least one portion of the optical fiber through photo-etching, photo-bleaching, ultraviolet radiation exposure or splicing. The optical fiber containing the random modulation is used to measure one or more engineering parameters by locating the section or portion of the optical fiber containing the random modulation in an area where the engineering parameter is to be measured and measuring the engineering parameter using optical frequency domain reflectometry.

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.
