    摘要: A method for optimizing the architecture of a linear sensor array using WDM-TDM technology and stabilizing the reflectivity spectral profile of the fiber Bragg gratings of the sensors against the influence of environmental factors such as pressure and temperature is provided. The method includes stripping a portion of the foamed coating on the exterior of an optical fiber in the region of the fiber Bragg grating to thin the coating in the region of the grating. After the coating is stripped and the optical fiber cleaned, the area of stripped fiber is recoated with an unvoided plastic.

    摘要: An optical detection system for monitoring a pipeline. The optical detection system includes a host node in the vicinity of, or remote from, a pipeline to be monitored. The optical detection system includes (a) an optical source for generating optical signals, and (b) an optical receiver. The optical detection system also includes a plurality of fiber optic sensors local to the pipeline for converting at least one of vibrational and acoustical energy to optical intensity information, each of the fiber optic sensors having: (1) at least one length of optical fiber configured to sense at least one of vibrational and acoustical energy; (2) a reflector at an end of the at least one length of optical fiber; and (3) a field node for receiving optical signals from the host node, the field node transmitting optical signals along the at least one length of optical fiber, receiving optical signals back from the at least one length of optical fiber, and transmitting optical signals to the optical receiver of the host node.
