Fiber optic vibration sensor for soil measurement

Fiber optic vibration sensor for soil measurement

In this paper, various technologies of distributed fiber-optic vibration sensing are reviewed, from interferometric sensing technology, such as Sagnac, Mach–Zehnder, and Michelson, to backscattering-based sensing technology, such as phase-sensitive optical time domain. 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. Optical parameters such as light intensity, phase, polarization state, or light frequency will change when external vibration is applied on the sensing fiber. The response of the DAS system to external vibrations varies with different types of fiber optic cable connections. A dual-purpose single mode optical fiber sensor was developed for simultaneous soil moisture and structural health monitoring.

Fiber Optic Sensor Design and Fabrication Methods

Fiber Optic Sensor Design and Fabrication Methods

This Special Issue focuses on the innovative design of optical fiber sensor structures, including fiber Bragg gratings, long-period gratings, interferometric sensors, and advanced micro-structured fibers. Optical fiber sensors are devices that use optical fibers to detect and measure various parameters such as temperature, pressure, strain, and refractive index. The apparatus includes a heating source (110) and a robotic articulate arm (130) that may modify the geometry of an optical fiber (150). Nowadays fiber optic refractive index sensors are widely used in various fields such as chemical, biochemical, and in an industry field. The optical fibre can be used as a distributed sensor by exploiting light scattering effects or as a quasi-distributed sensor network by functionalizing the fibre through Bragg gratings photo-inscription for instance.
