comparison of different glass compounds for intrinsic fiber optic temperature sensors

چکیده

different glasses suitable for temperature sensing in the fiber optic sensors were studied in this article. the phase changes for eight different glass materials were calculated and results were compared. our results showed that extra dense flint glass is the most sensitive one, while pure silica results in the lowest phase change. in another study the effect of wavelength on the phase variation was also investigated and the results were presented. finally, the effect of glass formation in phase change was considered for different glasses, which were prepared using different techniques. the result showed that the corning glass #7940 offers the highest sensitivity in comparison with the other three glasses for temperature sensing. our studies for different silica glasses indicated that glass formation is important in preparing the glass materials required for the fiber sensors.

Fiber Optic Distributed Sensors for High-resolution Temperature Field Mapping

The reliability of computational fluid dynamics (CFD) codes is checked by comparing simulations with experimental data. A typical data set consists chiefly of velocity and temperature readings, both ideally having high spatial and temporal resolution to facilitate rigorous code validation. While high resolution velocity data is readily obtained through optical measurement techniques such as par...

Fiber-Optic Chemical Sensors and Fiber-Optic Bio-Sensors

This review summarizes principles and current stage of development of fiber-optic chemical sensors (FOCS) and biosensors (FOBS). Fiber optic sensor (FOS) systems use the ability of optical fibers (OF) to guide the light in the spectral range from ultraviolet (UV) (180 nm) up to middle infrared (IR) (10 μm) and modulation of guided light by the parameters of the surrounding environment of the OF...

Interferometric Fiber Optic Sensors

Fiber optic interferometers to sense various physical parameters including temperature, strain, pressure, and refractive index have been widely investigated. They can be categorized into four types: Fabry-Perot, Mach-Zehnder, Michelson, and Sagnac. In this paper, each type of interferometric sensor is reviewed in terms of operating principles, fabrication methods, and application fields. Some s...
