摘要： A fibre optic sensor deployed on a fibre optic cable to a remote location, such as an oil or gas well. The sensor, which can sense any of a variety of parameters such as pressure, temperature, flow rate, strain, or chemical properties, is located within a sleeve. The sleeve is constructed from a low-friction material, such as polytetrafluoroethylene, glass, or ceramic. Further, the sensor can float on a high-density fluid that surrounds it, or sink in a low-density fluid that surrounds it.

摘要： An apparatus for sensing data from a remote optical sensor 16 has its frequency stabilised by balancing the outputs of narrow band filter 28 30, spaced about a desired frequency 36 positioned at about the 3db down points 40 of a broad band light source 10 using voltage control, current control or temperature control to vary the frequency of the wide band light source 10. Difference between the outputs through the two narrow band filters 28 30 can be used to drive an amplifier 48 to correct the frequency of the broad band light source. The outputs through the two narrow band filters 28 30 can be converted 52 to binary numbers and fed to a microprocessor 56 which is used, via analog conversion 60, to drive the amplifier 48. The broad band light source 10 can be pulse modulated 68 to provide temporally separate light pulses 92 94 through each of the narrow band filters 28 30, measured at separate times. The corrective output to the amplifier 48 can be governed by a ratio between the outputs through the narrow band filters 28 30 rather than by a difference there between.

摘要： A method and apparatus for receiving measurements from an interferometer transducer (22) uses a broad band light beam (19A), reflected from the transducer (22), and compares it with the amplitudes of narrow band beams, derived from the reflected broad band light beam (19A), by filters (23A-23D) on different frequencies. The narrow band light beams and the broad band light beam (19A) are measured on photo detectors (22A, 21B-21E). Microprocessor (57) compares outputs of the photo detectors to interpret phase differences between signals (25, 27, 29) from the narrow band beams. A periodically operable shutter and a single photo detector (21) can also be used. Other embodiments modulate (12) the light source (10) to produce very short broad band pulses of light (36, 40) which are reflected from the transducer (22).

摘要： A sensing fibre for use in a distributed temperature sensing system comprises an optical fibre to be deployed in a measurement region in which a temperature measurement is to be made, which incorporates a reflective element, such as a join between portions of fibre, and a coiled fibre portion positioned adjacent a distal side of the reflective element, the coiled fibre portion contributing substantially nothing to the spatial extent of the optical fibre when deployed. In use, the effect of any forward propagating light incident on the reflective element that is returned for detection by the system, and which saturates the detector, can be eliminated by removing the part of the detected signal that corresponds to the coiled portion, after which the detector will have recovered. The remaining parts of the signal can be used to derive the distributed temperature profile since these parts represent the whole extent of the sensing fibre owing to the lack of spatial extent of the coil. Coils can be provided on both sides of the reflective element for double-ended temperature sensing techniques.

摘要： A method for identifying the primary cell under Site Selective Diversity Transmit comprises the steps of: (1) An ID is assigned by the system to each cell; (2) The ID indicating the primary cell is transmitted periodically by UE to the connected cells via the up link FBI fields; (3) The ID indicating the primary cell transmitted by the mobile station is received by the base station, if the signals received by the base station satisfy with one of the following conditions, then the said base station will consider itself as a primary cell; the identification conditions are: A. The ID code word indicating the primary cell received by the base station is matched with the ID code word of itself; B. The quality of the up link signals received does not satisfy with a quality threshold Qth, at the same time, there is a certain matching degree between the received ID code word indicating the primary cell and the ID code word of the cell itself; and C. The bits of dropping of the ID code word caused by using the up link compression mode excess a limitation. The signals transmitted form some of the non-primary cells having extremely bad quality to UE can be prevented, thereby the system interference is reduced, and the system stability and the system capacity are increased.

摘要： A sensing system including a sensor having an enclosure that defines a chamber, a fiber optic segment extending from outside the enclosure into the chamber, and a sequence of optical processing elements within the chamber. The elements include a fiber Bragg grating, a polarizer, a side hole fiber, and a mirror. A light source is arranged to direct light to the sensor(s). A spectral analyzer is arranged to detect light reflected back from the sensor(s). The fiber Bragg grating substantially reflects a first spectral envelope while transmitting the remainder of the optical spectrum to the polarizer and side hole fiber. The polarizer, side hole fiber, and mirror cooperate to return an optical signal within a second spectra! envelope. The characteristic wavelength of a peak in the first spectral envelope is highly sensitive to temperature and relatively weakly sensitive to pressure. The period of the optical signal within the second spectral envelope is highly sensitive to pressure and relatively weakly sensitive to temperature. The spectral analyzer measures these spectral components to simultaneously derive a measure of temperature and pressure that effectively compensates for temperature-pressure cross-sensitivity of the sensor(s).

摘要： A multiple sensor fiber optic sensing system includes an optical fiber having at least first fiber optic sensors and second fiber optic sensors deployed along its length. In response to an interrogating pulse, the first fiber optic sensors generate responses in a first optical spectrum window, and the second fiber optic sensors generate responses in a second, different optical spectrum window. The responses in the first optical spectrum window are measured in a first optical spectrum channel, and the responses in the second optical spectrum window are measure in a second, different optical spectrum channel and provide simultaneous indications of one or more parameters, such as temperature and pressure, in the environment in which the sensors are deployed.
