Working Principle of Fiber Optic Microbending Sensor
Intensity modulation induced by microbending in multimode fibers is considered as a transduction mechanism for detecting environmental changes such as pressure, temperature, acceleration, and magnetic and electric fields. Fiber Optic Cable: Standard single-mode or multimode optical fibers are used. Multimode fibers are often preferred due to their higher sensitivity to bending. This can take various forms, but typically involves. Microbends are microscopic bends of an optical fiber, which can cause bend losses (bend-induced propagation losses) even when the fiber is macroscopically kept straight. Also, they influence the polarization mode dispersion. A generic microbend sensor has been defined and studied, and its components. This work proposes a highly sensitive sandwich heterostructure multimode optical fiber microbend sensor for heart rate (HR), respiratory rate (RR), and ballistocardiography (BCG) monitoring, which is fabricated by combining a sandwich heterostructure multimode fiber Mach–Zehnder interferometer. Microbending basics Microbending attenuation of an optical fiber relates to the light signal loss associated with lateral stresses along the length of the fiber.
