High-precision sensors based on doped optical fiber.
High-precision sensors based on doped optical fibers have a high sensitivity to changes of temperature, pressure, chemical composition, electromagnetic fields and radiation background. They are resistant to aggressive media and to electromagnetic disturbances that enables high-precision monitoring of remote large-scale objects.
Technology is in the process of development!
On the basis of fiber scientists have created high-precision Autonomous sensors. In this case, the optical fiber doped rare-earth and transition metals, erbium, holmium a, bismuth and silver nanoparticles and silicon. The composition and the ratio of ligands (chemical additives) in a quartz-based optical fiber of the original and provide unique properties of the obtained fibers and determined (detected) settings.
The resulting optical fibers have high sensitivity to changes of temperature, pressure, chemical composition, electromagnetic fields and radiation background. Optical fibres are resistant to aggressive media and to electromagnetic disturbances that enables them with high-precision monitoring of large-scale facilities (pipelines, wells, nuclear power plants, bridges) on a number of parameters. Set the fiber length to measure objects of large (up to hundreds of meters) size.
Fiber optic sensor is a or small, “spot” device, or “spatially-distributed circuit” that can collect information about parameters detected at large distances (“long” detector). In the format of “long” sensor sensitive element is the entire length of fiber used. The length of optical fiber enables remote remotely measuring, for example, full-scale monitoring of deep oil wells, mines, pipeline, units of nuclear power plants.
High-precision sensors based on doped optical fibers operate in two modes: “passive” (and then detektirovanie parameters are, for example, changes in the spectra of absorbance and transmittance of doped fiber) and “active” when the fiber is a component of the laser (and then detektirovanie parameters are, for example, the relaxation frequency, the optical spectrum or the generation mode of the laser).
