| 20110242525 | Redundant Optical Fiber System and Method for Remotely Monitoring the Condition of a Pipeline - An optical fiber sensor system and method for monitoring a condition of a linear structure such as a pipeline is provided which is capable of providing continuous monitoring in the event of a break in the sensing optical fiber or fibers. The system includes at least one sensing fiber provided along the length of the linear structure, and first and second interrogation and laser pumping sub-systems disposed at opposite ends of the sensing fiber, each of which includes a reflectometer. The reflectometer of the first interrogation and laser pumping sub-system is connected to one end of the sensing fiber. The reflectometer of the second interrogation and laser pumping sub-system is coupled to either (i) an end of a second sensing fiber provided along the length of the linear structure which is opposite from the one end of the first sensing fiber, or (ii) the opposite end of the first sensing fiber. Before any break of the sensing fiber or fibers occurs, each reflectometer redundantly monitors the condition of the linear structure over its entire length. After any such break occurs, each reflectometer will continue to receive signals up to the point of the break from opposite ends of the structure. | 10-06-2011 |

| 20090263069 | RAMAN AMPLIFICATION IN DISTRIBUTED OPTICAL FIBER SENSING SYSTEMS - A method of providing Raman amplification in an optical fiber sensing system, comprises generating a probe pulse of light and launching the pulse into a sensing optical fiber, generating pump light at a shorter wavelength and modulating it to produce a time-varying intensity profile, and launching the pump light into the sensing fiber. such that the intensity of the launched pump light during launch of the probe pulse is different from the intensity at other times. Raman amplification of backscattered light produced by the probe pulse as it propagates along the fiber is achieved, as is amplification of the probe pulse if the pump power is non-zero during launch of the probe pulse. | 10-22-2009 |
| 20100117830 | FAULT-TOLERANT DISTRIBUTED FIBER OPTIC INTRUSION DETECTION - An intrusion detection system for monitoring a premises includes at least one optical cable that houses at least one optical fiber and extends about the premises. Optical time domain reflectometry (OTDR) means is operably coupled to opposite first and second ends of the at least one optical fiber. The OTDR means includes first signal processing circuitry that analyzes the backscatter signal received via the first end of the at least one optical fiber in order to detect an intrusion of the premises, and second signal processing circuitry that analyzes the backscatter signal received via the second end of the at least one optical fiber in order to detect an intrusion of the premises. The redundancy of intrusions decisions made by the first and second signal processing circuitry can be verified. The system preferably further includes means for detecting a break in the at least one fiber, for identifying location of the break, for outputting to a user the location of the break, and for raising an alarm indicating the break. | 05-13-2010 |

| 20100165327 | MEASURING BRILLOUIN BACKSCATTER FROM AN OPTICAL FIBRE USING CHANNELISATION - A method for measuring Brillouin backscattering comprises obtaining a signal representative of backscattered Brillouin light received from a deployed optical fibre, and dividing the signal into a plurality of signal components each having a different frequency hand. Each signal component is delivered to one of a plurality of parallel detection channels, in which the components are detected, and the signal generated by the detection is sampled using an analog-to-digital converter. The samples are then processed to determine one or more properties of the Brillouin spectral line. Detection may be optical, where the backscattered light is dispersed into a plurality of optical frequency components, or electrical, where the backscattered light is first frequency mixed to downconvert the frequency to the microwave regime. | 07-01-2010 |
