FIBER OPTIC SENSORS FOR LIQUID LEVEL MEASUREMENT

Fiber Optic Counting Liquid Level Sensor

This technology, known as WLPI (White Light Polarization Interferometry), operates using the phase modulation of light — the most sensitive method for fiber-optic measurements. Hydrostatic pressure measurement with optical sensors enables precise long-term monitoring of liquid. In this paper, a novel liquid level sensing system is proposed to enhance the capacity of the sensing system, as well as reduce the cost and increase the sensing accuracy.

Embedded Design of Fiber Optic Sensors

This work proposes a novel method of embedding FOSs using capillaries within solid structures and investigates fiber positions and orientation uncertainties within capillaries of different sizes and their influences on strain measurement accuracies. Embedding fiber optic sensors (FOSs) within parts for strain measurement is attracting widespread interest due to its great potential in the field of structural health monitoring (SHM). Therefore, the purpose of this effort is to bridge the gap between civil engineering and sensor engineering communities through an overview on the up-to-date technological advances in both sectors, with a special focus on textile reinforced concrete embedded with fiber optic sensors.

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.
