A multitude of structural health monitoring options are currently being investigated to
address the reliability of concrete infrastructures at different stages of their service life. This …

Oil and gas pipelines are very important for fuel transportation, however leakages in them
may lead to life and property losses due to the release of the energy they contain. Reliable …

High-temperature measurements above 1000° C are critical in harsh environments such as
aerospace, metallurgy, fossil fuel, and power production. Fiber-optic high-temperature …

A hybrid cascaded configuration consisting of a fiber Sagnac interferometer (FSI) and a
Fabry-Perot interferometer (FPI) was proposed and experimentally demonstrated to …

Reliable and accurate measurements of temperature and strain in structures subjected to
fire can be difficult to obtain using traditional sensing technologies based on electrical …

In-line fiber optic interferometers have attracted intensive attention for their potential sensing
applications in refractive index, temperature, pressure and strain measurement, etc. Typical …

This paper presents a polymer optical fiber (POF)-based temperature sensor. The operation
principle of the sensor is the variation in the POF mechanical properties with the temperature …

We demonstrate an all-fiber optical Fabry–Perot interferometer (FPI) strain sensor whose
cavity is a microscopic air bubble. The bubble is formed by fusion splicing together two …

Based on the characteristic of magnetic-controlling refractive index, the magnetic fluid filled
in hollow-core photonic crystal fiber (HC-PCF) can be used as the sensitive medium in the …

On the oil production also involves the production of water, gas and suspended solids,
which are separated from the oil on three-phase separators. However, the control strategies …
