Fibre optic sensors offer complete immunity to RF and microwave radiation with high temperature operating capability, so they can be used for measurement on patients and materials in magnetic resonance scanner (MRI). In strong magnetic fields, there is a small offset in the temperature reading approximately proportional to the strength of the ...
Distributed temperature sensing systems (DTS) are optoelectronic devices which measure temperatures by means of optical fibres functioning as linear sensors. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile.
Optical fiber sensors for temperature and pressure have been developed for downhole measurement in oil wells. [8] [9] The fiber-optic sensor is well suited for this environment as it functions at temperatures too high for semiconductor sensors (distributed temperature sensing).
Luna Innovations holds more than 450 U.S. and international patents in fiber optics and specializes in products for fiber-optic testing of components, modules and networks, as well as integrated optics and distributed fiber-optic sensor solutions. Their fiber-optic test and measurement devices include optical analyzers, reflectometers, tunable ...
Rayleigh scattering-based distributed acoustic sensing (DAS) systems use fiber optic cables to provide distributed strain sensing. In DAS, the optical fiber cable becomes the sensing element and measurements are made, and in part processed, using an attached optoelectronic device. Such a system allows acoustic frequency strain signals to be ...
