摘要： Systems and methods for extending the range of a fiber optic DTS system are provided. In one respect, a method may provide steps for transmitting, in a first time period, an optical signal at a first energy level through an optical fiber, collecting backscatter signals as a result of the first transmission, adjusting the first energy level to a second energy level, transmitting, in an additional time period, the adjusted optical signal through the optical fiber, collecting backscatter signals as a result of the adjusted transmissions, and using a portion of the collected backscatter as a result of the first transmission and a portion of the collected backscatter as a result of the additional transmissions, determining one or more parameter profiles, such as a temperature profile.

摘要： Systems and methods for calibrating a temperature sensing system are disclosed. In one respect, a dual light source configuration may be provided. A first light source may illuminate a sensing fiber and an anti-Stokes band may be detected. A second light source may illuminate a sensing fiber and a Stokes band may be detected, where the Stokes band is substantially similar to the anti-Stokes band of the first light source. A ratio between the anti-Stokes and Stokes band may be used to calibrate a temperature sensing system.

摘要： A distributed sensing system for detecting partial electric discharge along the length of an extended object or objects. An optical fiber having a cladding integrated with luminescent material and a silica core of less than 500 micro-meters in diameter with a first reflective end deployed in proximity to test objects. A photo detector is positioned at the second end of the optical sensing fiber and receives and measures both a direct emission light from an electric partial discharge event and the reflected emission light from the reflection end of the optical sensing fiber. The measured signals and their arrival times are used to determine the location and magnitude of a partial electrical discharge.
