ABSTRACT:
New types of fiberoptic microbend sensors are in the form of flexible tapes wherein single or multiple layers of mechanically tough flexible tapes form two outside surfaces of the sensors including between them one or more continuous elongated optical fibers, a variety of monofilaments, wires, threads, meshes, ribbons and or like elements to act as deformers to the optical fiber and sufficient adhesive material to form a permanent flexible tape structure. Additional layers of film, optical fibers, and/or deformer elements may be included to augment or modify the intensity of light that issues from the output end of the optical fibers when they are illuminated at their input end while the surface films of the sensor are subjected to pressure, such as when the sensors are used to weight or detect passage of automobiles. Detection or measuring systems and methods using the flexible sensor tapes are disclosed.
