Latest Patents
One of Stewart D Personick's latest patents is focused on the microbending of optical fibers for remote force measurement. This innovative system includes a plurality of microbend transducers mounted along the length of a structure, which microbend an optical fiber in response to structural forces. The technology is particularly useful for measuring stress acting upon oil or gas pipelines. An optical time domain reflectometer (OTDR) is employed, featuring a light source that launches a pulsed optical signal through the fiber. A photodetector senses the intensity of backscattered light, which is correlated with discrete longitudinal positions along the fiber and the structure. When microbend transducers are activated, they induce a microbend in the fiber, resulting in a loss of backscattered light intensity. This attenuation is quantitatively sensed and positionally identified by the photodetector, allowing for precise detection of structural strain.
