Vibrating Optical Cable Circuit
Abstract – Vibration causes mechanical distortions in fiber-optic transmission lines that induce time (phase) fluctuations. Fiber optic vibration sensors that use existing fiber optic cables laid for communication have the advantage of being able to collectively and accurately measure vibrations over a wide range along the cables1), 2), and in recent years, they have been attracting attention as a means of environmental. Unlike traditional point-type vibration sensors, DVS realizes continuous, real-time. However, lack of experimental data on actual machinery in comparison to test bench devices, has made it difficult for a reliable fault detection and lifetime assess-ment. RF systems are increasingly using optical fibers in various ways and must occasionally operate in environments with acoustic and structure-born vibration. The ability to easily and economically acquire and synchronize multiple high-precision fiber optic accelerometer measurements brings the benefits of fiber optic sensing to a wid ding precision and sensitivity.
