MICROBENDING OF OPTICAL FIBERS FOR REMOTE FORCE MEASUREMENT
专利汇可以提供MICROBENDING OF OPTICAL FIBERS FOR REMOTE FORCE MEASUREMENT专利检索，专利查询，专利分析的服务。并且A system for remote measurement of structural forces includes a plurality of microbend transducers (14) mounted along the length of the structure (12) for microbending an optical fiber (16) in response to structural forces, such as stress acting upon an oil or gas pipeline or the like. An optical time domain reflectometer (OTDR) (18) has a light source (46) for launching a pulsed optical signal passage through the fiber and a photodetector (56) for sensing as a function of time the intensity of backscattered light reflected back through the fiber, wherein this sensed time function is correlated directly with discrete longitudinal positions along the length of the fiber and the structure. When one or more of the microbend transducers is activated to induce a microbend in the fiber response to localized forces acting upon the structure, a portion of the backscattered light is lost at the microbend. This attenuation in backscattered light intensity is sensed quantitatively and positionally identified by the photodetector. Specific preferred constructions for microbend transducers and system arrangements particularly adapted for detecting structurally strain in an oil or gas pipeline are disclosed.，下面是MICROBENDING OF OPTICAL FIBERS FOR REMOTE FORCE MEASUREMENT专利的具体信息内容。
